Try it yourself: if you have e.g. a triangle containing a table, then
they simply write the content of the table (but not the table itself) to
ODF, to produce valid ODF. That's a discussion for an other proposal,
though.

So you propose to add a fake paragraph and a fake frame to hack in a
table into a shape content when you describe that in ODF, instead of
simply allowing table:table inside e.g. draw:custom-shape? That sounds
suboptimal to me. :-) But again, this is not proposed yet, so outside of
the scope of the current discussion.

Please be aware of that LO's xmloff uses a SAX parser, so this is not
easily possible. This list is to discuss patches to the LO codebase, not
to discuss theoretical problems. ;-) (Or instructing developers what
their implementation should do.)

However, now that you mentioned that an alternative way to describe a
shape with a TextBox is to (mis-)use some existing ODF markup, instead
of using an explicit new optional attribute, I reimplemented sw
textboxes in xmloff in commit 9835a5823e0f559aabbc0e15ea126c82229c4bc7.
It uses the same (somewhat ugly) trick how we detect draw vs sw shapes,
just in this case for the content of customshapes.

HTH,

Miklos
