When you say you "change it to 1.0", do you mean that you change the version
number in the xsl:stylesheet element, or that you change the XSLT processor
you are using, or both?

it hits the same file it hung up on with 2.0, it transforms in a second or two
with 1.0. The XSLT does not use any 2.0 capabilities yet. The only change is
changing 2.0 to 1.0 in <xsl:stylesheet version="2.0">.

I am converting an HTML-based publishing output from a much older version of
the DITA OT, 1.8.5 (where the code worked). It looks like the 3.3.2 OT uses
