If you're trying to avoid the extra key strokes then I'd agree with Thomas's
answer that there is no way around it (IMHO).

However, if you're generating the XSL documents by some software and you
don't care about human readability then try this (I haven't tried it, but it
might work):


<xsl:value-of xmlns="http://www.mydomain.org/ns/" select="request/title"/>


   Basically, define the default namespace in each and every XSLT tag where
there is an XPath expression. Cumbersome and ugly, but it's another
solution.

You can't really avoid having a namespace prefix in the xpath 
statements, because xpath knows nothing about any default namespaces. 
So if the elements you want to select are in a given namespace, then the 
xpath expressions must explicitly contain a prefix that puts the 
elements into that namespace.

Cheers,
