It certainly doesn't have to validate but a conforming XSLT processor 
*must* read the external DTD subset. The reason is that the XPath 
data model does not allow unresolved entity references. If any of 
these are defined in the external subset, then you can't build a data 
model for the document without reading the external subset.
