The <specifier> Element
The <specifier> tag is a container for all of the part action elements in the part specification. The <specifier> tag is the very first tag in the part specification definition and the </specifier> is the very last. All other elements in the part selection criteria reside between the two <specifier> tags.
Usage Example:
<specifier>

<PartAction>
