Step 4: Matching <epm-iba> without ‘value’ attribute present
Evaluation continues by searching the children of the <authoring-application> element matched in Step 1 for a <epm-iba> element whose ‘iba’ attribute matches to a global attribute name within the EPMDocument.
* 
The ‘value’ attribute of <epm-iba> is an optional attribute; Step 4 only considers those <epm-iba> elements whose ‘value’ attribute is not present. The <epm-iba> elements that meet this criterion are considered in the order they appear in the Publish Rules XML file.
<authoring-application name=”MY_AUTH_APP”>
<epm-iba iba=”IBA_NAME_1”>
*
*
*
</epm-iba>

<epm-iba iba=”IBA_NAME_2”>
*
*
*
</epm-iba>
</authoring-application>
If a match is found, the matched <epm-iba> element becomes the root for searching for <publish> elements, which are described in Step 8; otherwise, evaluation proceeds to Step 5.
