Note "xsl": ^^^
It sounds as if your application is written in XSLT. If so, at
least the way most XSLT applications are configured, the "xsl:"
prefix is important. Most (all?) XSLT processors associate "xsl:"
with the XSLT namespace by default. See section 2.1 of the XSLT
recommendation at (http://www.w3.org/TR/xslt#xslt-namespace) for
The XSLT namespace has the URI http://www.w3.org/1999/XSL/Transform.
This specification uses a prefix of xsl: for referring to
elements in the XSLT namespace. However, XSLT stylesheets are
free to use any prefix, provided that there is a namespace
declaration that binds the prefix to the URI of the XSLT
If you are going to use "abc:" (or anything else) instead of
"xsl:" for the prefix for XSLT elements in an XSLT application,
you'll need to start your stylesheet with
However, unless you have a good reason to use something other than
the "xsl:" prefix for the XSLT elements, you'll be better off if
you stick with "xsl:" -- no reason to confuse anyone who might
need to modify or maintain your applications or reuse portions
