Subject: Complex content inside shapes
Hi all,
LibreOffice has implemented the ability for complex content in shapes. I
would not bother you with this, but it will result in requests for
ODF1.3. Therefore I ask you to have a look and help me to form an opinion.

Can you say more on how you think this is already possible
in ODF 1.2 without any required change? Or are you saying
there is an implementation-defined case already available
under ODF 1.2?
In the second case, it would seem simpler to agree on a
shared implementation-defined (and public) definition than
to expect incorporation in a new ODF specification. For one
thing, that doesn't do anything for ODF 1.2-conforming documents.
Did the LibreOffice extension presume to reuse an OASIS namespace
or was it done properly with a well-defined foreign extension?
(1)
I became aware of the problem with
https://issues.oasis-open.org/browse/OFFICE-3864. In the meantime the
developer found another way to track, whether the shape has "complex"
content. So the request for a new attribute has been (or will be?)
canceled. But he is not really satisfied with the solution.
(2)
When a custom shape contains a table then LibreOffice currently writes e.g.
<draw:custom-shape ...>
<table:table...>
...
</table>
<text:p ...>
...
</text:p>
<draw:enhanced-geometry ...>
...
</draw:custom-shape>
This solution is not valid in ODF1.2. A construction of the kind
<draw:custom-shape>
...
<text:p>
<draw:frame>
<table:table>
...
</table:table>
</draw:frame>
</text:p>
...
</draw:custom-shape>
would be valid.
In normal texts <table:table> and <text:p> are both allowed as child of
<office:text>. Here a <table:table> element in a <draw:frame> has a
different meaning, because its outside the text flow. But inside a shape
the table is already outside the text flow and putting it into a
<draw:frame> would not add restrictions.
The comment of the developer is in
https://bugs.freedesktop.org/show_bug.cgi?id=84714#c1. He suggests to
write loext:table till the proposal of <table:table> as child of
<draw:custom-shape> is accepted. He dislikes "fake" use of
<text:p><draw:frame> as wrapper. In addition he mentioned in the
discussion [4] on the mailing list, that because LibreOffice (and same
OpenOffice) use a SAX parser, it can not easily be detected, whether
elements exist or not exists in a sub-tree of the XML tree. I'm not able
to judge this.
Is the idea to allow <table:table> as child of <draw:custom-shape> and
other shapes worth supporting?
Kind regards
Regina
