Re: [xsl] Resolving xsl:import href on different base URIs

Two further tricks:

(a) when you load the top-level stylesheet using new StreamSource(stream, 
systemId), the systemId becomes the base URI of the top-level stylesheet 
module, and this doesn't need to reflect the actual location of the source code.

(b) don't forget that you can set xml:base="" on either the xsl:stylesheet 
element or the xsl:import element,
