ITS2XLIFF generation update - within text

Hi all,

I worked a bit on the ITS2XLIFF generation. See
http://fabday.fh-potsdam.de/~sasaki/its/temp.html for a temporary position
for a new which "understands" both its:translate and "elementsWithinText".
If an element is translatable and not within text, a separate trans-unit  is
generated. See an example input at
http://fabday.fh-potsdam.de/~sasaki/its/its-general-decorator-07/sample/input.xml-
verbatim is translatable, but not within text.

Working on this I started wondering if withinText="nested" is really needed,
since you can infer it from the combination of the values "no" and "yes": if
an element A is not within text and is nested in an element B also not
within text, that means that A is "nested". Any thoughts on this?

Best,

Felix
