XLIFF Filter: CDATA markup stripped in Memsource tag

[Phil Ritchie]

This issue is very similar to #613.

Attached is a file produced by Memsource. It contains a CDATA markup embedded in a custom <m:open-mark-content> element.

When parsed through the XLIFF Filter, the markup is stripped and the embedded content is written out and the resulting file is invalid (see the "afterXLIFFFilter.xliff" attachment).

Huh, weird. This is in skeleton, I wonder why the fix for #613 isn't working.

Marta fixed this in M34 -- see commit 6019bb7f and related work.
