if each package descriptions was separated from its respective installation script then it provides a fairly powerful means of locating packages.
1. the src attribute to a <config/> widget could be a composite reference identifying several package distribution sites 2. the addition of a 'packageType' description field would allow selective searching <RDF:Description PACKAGE:packageName="xyz" PAGKAGE:packageVersion="1.1.1." PACKAGE:packageAuthor="Mozilla.org" PACKAGE:packageNote="This package does xyz and .........." PACKAGE:packageType="plug-in" PACKAGE:fileName="xyz.xpi" PACKAGE:fileSource="http://www.mozilla.org/installation " PACKAGE:fileSize="1.2" /> so for then for example it would be possible to list only 'plug-in' packages using standard tree item selection criteria
