7.0.1 HR fix: Bug 197467 - 20s-60s - xml.retriever.catalog.impl.CatalogModelImpl.getModelSource()

     *http://netbeans.org/bugzilla/show_bug.cgi?id=197467*

http://hg.netbeans.org/web-main/rev/3a94f1d7edd0

Description: Invoking the code completion in XSL files w/o the 
schamaLocation attribute blocks the completion for long time and finally 
doesn't work at all.

Evaluation: If the xsl document only declares the 
http://www.w3.org/1999/XSL/Transform namespace, the normal xsl code 
completion model  workflow is broken since no schema is specified. Some 
kind of "last resort" solution is used - download the resource specified 
by the identifier (and not to cache it) and try to pass it to the schema 
model. Since the link points to some html document describing the 
namespace, the schema model is not properly built.

Fix: In the xsl documents described above the XSL namespace declaration 
is checked and if the version attribute in the declaring tag has 2.0 
value the proper xslt schema is loaded and cached. If the xslt version 
is 1.0 some kind of pseudo DTD grammar is used instead (xslt1.0 has no 
proper DTD nor schema).

Thanks,
Marek
