	Description:

	Create a stand-alone sysdef from a linked set of fragments, paring down to just a set of items of the desired rank.

-->

 	<xsl:output method="xml" indent="yes"/>

<!--Description:This pares the generated sysdef down to just a set of items of the desired

rank. In other words, you provide a list of IDs to keep and a system model

rank (layer, package, collection, component). 

Every item of that rank in the sysdef will be removed except those in the list

of IDs.

Primary use cases of this would be to extract a single layer, or to select a

specific set of packages.
