[wtp-dev] Submission for PMC approval (1.5.1) 157731 - TaglibIndex retur

[Nitin Dahyabhai <nitind@xxxxxxxxxx>]

The TaglibIndex has two major APIs,
one for finding TLDs and another for enumerating the visible TLDs.  To
support the "implicit" TLDs mentioned in the JSP spec, we're
employing the XML component's XML Catalog.  The ITaglibRecords it
returns should  provide URI values for use within a JSP's taglib directive,
but records built from the catalog were returning either the wrong URI
value, or no value at all.  This affects adopters that want to accurately
make use of the enumeration facility (to guide editing) and server adapter
 providers that want to provide value added tag libraries unique to
their server.

The patch attached to the bug ensures
for resolving TLDs, records returned from a successful lookup in the XML
Catalog report the key that was used for the catalog lookup as the URI.
 For enumerating TLDs, the patch makes the URI values reflect the
keys in the XML Catalog extension point.  The patch has been tested
by an adopter already and is only a minor change from 1.5.1 RC1.
