Subject Re: HSSFSerializer - Extensions?
Date Tue, 31 Dec 2002 16:14:48 GMT
We're amenable to extensions to the existing format.  Moreover
gnumeric is going to be making a jump to a new wrapper format
shortly at which time I hope to make larger scale changes to
the xml representation and would appreciate any feedback you have on
limitations or irritations in the current schema.

I'd be interested in a list of the others.  Adding this would be
simple and would give me some insight into what sorts of features
real users are looking for.

Requires conversion by what ?

I just added it in about 10 seconds.  The extension will be in
1.1.15, and is trivial enough that I could back port it to be in the
next stable release 1.0.12.
