That would not be viewed with favour.

Yeah. The core issue here is to not set off false positiives from change
detection in a linewise, rather than node-aware, diff process in a
source control system. Any fragile special processing is not likely to
help in this respect.

Can't mark a variable defined using xsl:map as static, which I would at
least like to be able to do. (Which makes sense; the XPath map is text,
xsl:map contains a sequence constructor.)

This would not appear to be a viable option.

I'm now wondering if I can hive all the variable definitions off into
a file I include but need not auto-update with the instance number.
That hasn't been an option before but I am no longer required to use SEF
files to deploy the transform.

Thanks!
