Re: [xsl] How can the mere switch from DTD to XSD in the source document affect how a stylesheet handles white space?

No. it's a difference between XSLT 1 and 2, and DTD-less vs. with a
DTD. The _only_ whitespace that can officially be dropped by an XML
parser is when a DTD is in use and the DYD says an elememt only has
elmeent children, not #PCDATA. oher schemas, such as W3C XSD or
RelaxNG, are processed _after_ the XML is parsed and such spaces have
been (or not been) dropped based on the DTD.

What is processor-dependent is ways to mitigate this when it's a
difficulty.

Note (there was another thread on this recently) that a language
defined in XML can say that white-space in certain context is ignored,
as happend when an XSLT stylesheet itself is read.
