RE: [xsl] Whitespace around comments

---

---

In XSLT 1.0, with <xsl:output method="xml" indent="yes">, you are pretty
much at the mercy of the implementation. If you care about whitespace, don't
use indentation.

XSLT 2.0 is stricter, but it still says nothing about this case -
implementations can insert whitespace between a comment node and a start or
end tag, though they are advised against it if the content model is known to
be mixed.
