Re: ODF specification for border around text portions

Hi Regina

Thanks for bringing this up.

What would be nice to have is an equivalent feature of the "between" border
element, as described in [1]

An example document using this is in bug #104345 [2] and we currently don't
seem to have a similar feature neither on the UI nor in ODF.

So, if we could have a copy of this, that could be good for
interoperability.
