DESCRIPTION="""Expand the specified target definition template as follows: | ||
All 'location' elements must contains a valid 'repository' element with a | ||
'location' attribute. If a 'location' element does NOT contain 'unit' | ||
elements then the P2 repository is queried for all features using | ||
the expression 'Q:group'. The 'location' element is then filled with 'unit' | ||
elements for the latest version of each feature contained in the repository. | ||
If a 'location' element contains one or more 'unit' elements then the P2 | ||
repository is queried for all installable units (IUs). The 'unit' elements | ||
must specify an 'id' attribute, but the 'version' attribute is optional. | ||
If the specified IU is found in the repository then the 'version' attribute | ||
is either completed or verified. | ||
