xsltprocNewlineOutputHack - emits a single new line.
Hack Alert! This template helps xsltproc split up the output text elements
and avoid reallocating them into the MB range. Calls to this
template is made occationally while generating larger output
file. It's not necessary for small stuff like header.
The trick we're playing on xsltproc has to do with CDATA
and/or the escape setting of the xsl:text element. It forces
xsltproc to allocate a new output element, thus preventing
things from growing out of proportions and slowing us down.
This was successfully employed to reduce a 18+ seconds run to
around one second (possibly less due to kmk overhead).
