Indeed. For that matter, how is an XSLT processor to know that an arbitrary 
string (attribute value, #PCDATA, whatever) is even a URI to begin with? 
The "this is a URI" meaning is not inherent in any XML vocabulary (except, 
of course, XHTML). Someday no doubt an XLink-aware XSLT processor will come 
along and "know" that any value of an xlink:href attribute must be a URI. 
Until then, I think it's a case of caveat author.
