I think XML can be a storage format for TS, but not the right way to 
create TS.
TS as cryptic is it is right now should not be written in XML like shown 
above,
it greatly reduces readability... unless we create a XML editor in typo3 
to create TS..

I think a good way would be using OBTS (never used it yet but always 
wanted to) and using a
syntax parser as suggested above.

just my 2 cents.
