Evaluation continues in Step 7 by searching the children of the <authoring-application> element matched in Step 1 for a <structure-type> element whose type attribute matches to the type of structure being published. The value of the type attribute can be epm, part, epm_plus_parts, part_and_epm, epm_wc_structure, epm_wc_structure, or type_based_object_structure. Steps 2 through 6 determine a root for searching for <publish> elements. This root can be an <epm-number>, <epm-iba>, <epm-type>, or <authoring-application> element.

If a match is found, the matched <structure-type> element becomes the root for searching for <publish> elements; otherwise, the <authoring-application> element becomes the root for searching for <publish> elements. In this case, the <authoring-application> element can be thought of as the “fall through” condition described in Step 6. Searching for <publish> elements is described in the next step.
