How to Flag DITA Content in WebHelp Output

Flagging content in WebHelp output involves defining a set of images that will be used for marking content across your information set.

To flag DITA content, you need to create a filter file that defines properties that will be applied on elements to be flagged. Generally, flagging is supported for block elements (such as paragraphs), but not for phrase-level elements within a paragraph. This ensures that the images that will flag the content are easily scanned by the reader, instead of being buried in the text.

Using a Publishing Template

To flag content in DITA Map to WebHelp output using an Oxygen Publishing Template, follow this procedure:

Create a DITA filter file (DITAVAL) and add it in a directory of your choice (for example, named myFile.ditaval.
Define the property for the elements you want to be flagged. For example, if you want to flag any element that has the @audience attribute set to programmer, the content of the DITAVAL file should look like this:
```
<?xml version="1.0" encoding="UTF-8"?> 
<val>
  <prop att="audience" val="programmer" action="flag"
 img="D:\resource\delta.gif" alt="sample alt text"/>
</val>
```
Note: For an element to be flagged, at least one attribute-value pair needs to have a property declared in the DITAVAL file.

Open the template descriptor file associated with your publishing template and add the args.filter parameter in the parameters section with its value set to the path of the DITAVAL file you created.

<publishing-template>
    ...
    <webhelp>
        ...                
        <parameters>
            <parameter name="args.filter" value="resources/myFile.ditaval"/>
        </parameters>
    </webhelp>

<val>
  <prop att="audience" val="programmer" action="flag"
