copy-of doesn't escape anything. In teh result tree formed by xslt the 
character isn't esacaped. Then when the result tree is serialised it may 
or may not be escaped at the choice of the XSLT system (but this choice 
will be for all < without any knowledge of whether it came from copy-of.

Most likely the well known non-conformance of msxml which discards all 
white space text nodes. Stick xml:space="preserve" at the top level of 
your output document to avoid this. (generate it with <xsl:attribute 
name="xml:space", don't put a literal xml:space attribute in your 
stylesheet.

yes
