> But aren't XML schema's XSL elements?

No, they are XML elements, XSL is the stylesheet and transformation
language for XML.
the DLL used by default in internet explorer 5 (msxml) does include
an XML parser, an XDR (XDR=Microsoft flavoured XML schema) validator,
and an XSL system (or at least Microsoft implementation of an early XSLT
draft). But these are all essentially different functionalities and
languages even though they are packaged up in one library in that
implementation.
