topicref-atts, topicref-atts-no-toc, and topicref-atts-without-format attribute groups

The "topicref-atts", "topicref-atts-no-toc", and "topicref-atts-without-format" attribute groups represent collections of attributes used in numerous map elements. With two exceptions, the three groups are identical. Neither "topicref-atts" nor "topicref-atts-without-format" provides a default for the toc attribute, while "topicref-atts-no-toc" provides a default of "no". Both "topicref-atts" and "topicref-atts-no-toc" include the format attribute, while "topicref-atts-without-format" omits the format attribute to allow specialization authors to declare the format attribute with specific default values.

Attributes

Note: The table below describes the "topicref-atts" attribute group. The "topicref-atts-no-toc" group is the same, except for the toc attribute, which is modified to provide a default of "no". The "topicref-atts-without-format" group is also the same as "topicref-atts", except that it does not define the format attribute.

Name	Description	Data Type	Default Value	Required?
collection-type	Collection types describe how links relate to each other. The processing default is "unordered", although no default is specified in the DTD or Schema. unordered Indicates that the order of the child topics is not significant. sequence Indicates that the order of the child topics is significant; output processors will typically link between them in order. choice Indicates that one of the children should be selected. family Represents a tight grouping in which each of the referenced topics not only relates to the current topic but also relate to each other. -dita-use-conref-target See Using the -dita-use-conref-target value for more information. Usage of the collection-type attribute on <reltable> and <relcolspec> is currently undefined and reserved for future use.	(unordered \| sequence \| choice \| family \| -dita-use-conref-target)	#IMPLIED	No
processing-role	Describes the processing role of the referenced topic. The processing default is "normal". If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor. normal Normal topic that is a readable part of the information. resource-only The topic is used as a resource for processing purposes, but is not a readable unit of information on its own. This topic should not be included in a rendered table of contents, and the topic should not be rendered on its own. -dita-use-conref-target See Using the -dita-use-conref-target value for more information.	(normal \| resource-only \| -dita-use-conref-target)	#IMPLIED	No
type	Describes the target of a reference. See The type attribute for detailed information on supported values and processing implications.	CDATA	#IMPLIED	No
scope	The scope attribute identifies the closeness of the relationship between the current document and the target resource. See The scope attribute for more information on values.	(local \| peer \| external \| -dita-use-conref-target)	#IMPLIED	No
locktitle	If locktitle is set to "yes", the <navtitle> element or @navtitle attribute is used if it is present. Otherwise, the navtitle is ignored and the navigation title is retrieved from the referenced file. Note: The @navtitle attribute is deprecated in favor of the <navtitle> element. When both a <navtitle> element and a navtitle attribute are specified, the <navtitle> element should be used. yes The navtitle in the map is used. no The navtitle or title of the topic is used. This is the processing default. -dita-use-conref-target See Using the -dita-use-conref-target value for more information.	(yes \| no \| -dita-use-conref-target)	#IMPLIED	No
format	The format attribute identifies the format of the resource being referenced. See The format attribute for details on supported values.	CDATA	#IMPLIED	No
linking	Defines some specific linking characteristics of a topic's current location in the map. If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor. targetonly A topic can only be linked to and cannot link to other topics. sourceonly A topic cannot be linked to but can link to other topics. normal A topic can be linked to and can link to other topics. Use this to override the linking value of a parent topic. none A topic cannot be linked to or link to other topics. -dita-use-conref-target See Using the -dita-use-conref-target value for more information.	(targetonly \| sourceonly \| normal \| none \| -dita-use-conref-target)	#IMPLIED	No
toc	Specifies whether a topic appears in the table of contents (TOC). If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor.	(yes \| no \| -dita-use-conref-target)	#IMPLIED	No
print	Specifies whether the topic should be included in a print-specific rendition, such as PDF. The processing default is "yes". If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor. yes Include the topic in the print-oriented file. no Do not include the topic in a print-oriented file. printonly Only include the topic when rendering the DITA content in a print-oriented context; the topic should not be included in other contexts, such as when rendering as HTML. -dita-use-conref-target See Using the -dita-use-conref-target value for more information.	(yes \| no \| printonly \| -dita-use-conref-target)	#IMPLIED	No
search	Describes whether the target is available for searching. If the value is not specified locally, but is specified on an ancestor, the value will cascade from the closest ancestor. yes no -dita-use-conref-target	(yes \| no \| -dita-use-conref-target)	#IMPLIED	No
chunk	When a set of topics is transformed using a map, the chunk attribute allows multi-topic documents to be broken into smaller files and multiple individual topics to be combined into larger combined documents. For a detailed description of the chunk attribute and its usage, see Chunking in the DITA Architectural Specification.	CDATA	#IMPLIED	No
