The <topic> element is the top-level DITA element for a single-subject topic or article. Other top-level DITA elements that are more content-specific are <concept>, <task>, and <reference>.
ditaarch:DITAArchVersion="1.0" xmlns:ditaarch="http://dita.oasis-open.org/architecture/2005/"In DTDs, the "ditaarch" prefix is parameterized to enable future specialization.
All DITA elements take the xmlns="" fixed attribute, which puts them into the null namespace by default. This attribute is applied via the %global-atts; group.

|Name||Description||Data Type||Default Value||Required?|
|id||An anchor point. This ID is the target for references by href and conref attributes, and for external applications that refer to DITA content.||ID||#IMPLIED||No|
|conref||This attribute is used to reference an ID on a topic that can be
reused. For example, you could create a series of topics in a compound (dita)
or nested context for authoring convenience and then reference each topic
individually into a new target location. During output processing, a lookup
process will pull the contents of the first topic into the calling topic markup
that has the conref attribute.
The conref value follows the same conventions as HTML for normal file links. To refer to target content in a different file, put the full URL of that topic before the # character.
Target elsewhere in the same file: conref="#topicid" First topic in different file: conref="filename.xml" Specific topic in different file: conref="filename.xml#topicid"

|xml:lang||Specifies the language of the element content. When no xml:lang value is supplied, the default value of English is assumed. For example, if there is a note element with the attribute xml:lang set to the value "es-es," then the label on the note, which is normally output as "Note" is now output in Spanish as "Nota." The allowed xml:lang values are based on ISO-3166 Country Codes and RFC 3066 Language Codes (see W3C: Language tagging in HTML and XML).||NMTOKEN||#IMPLIED||No|
