%select-atts;

Attributes that support both filtering and flagging include platform, product, audience, and otherprops. Attribute rev only lets you flag information that matches a run-time parameter. Attribute importance currently provides output effects only for steps (where only the values "optional" and "required" are supported).

Example

The %select-atts; parameter entity is used within the DITA dtds as a common definition for attributes available to most elements for you to enable the content for improved retrievability or for selection. Some typical examples include:

The <keyword platform="Linux">chmod</keyword> command...
<ph product="WhiteknuckleHandsoap">Amalgamated Cleansers get the grime!</ph>
<msgph audience="programmer administrator">Divide by -1 error.</msgph>
<ph otherprops="java">When using Java, use the 
  <apiname>com.ibm.obscureclass</apiname> to calculate the value.</ph>
<p importance="recommended" rev="3.2">Update anti-virus software often.</p>

Note that most of the attributes allow multiple values, for example the audience attribute in the example indicates that the message is of interest to both programmers and administrators.
