Re: [xsl] How to specify the range of possible values for font-size attribute

[Alexander Chingarev <alexander.chingarev@xxxxxxxxx>]

Thank you Liam. It's interesting to know that copyfitting is already
implemented by someone else. When we started working on it we did
search for FOP solutions but found nothing.

Is it possible to know more about that implementation? Which
adjustable attributes do they support, which limitations do they use?
And is it going to become a part of new FOP release?

Kind Regards,
Alexander

There's already a FOP implementation of it done at the University of
Bologna. But please do understand that the "specification" is only a
working draft, and is very much subject to change.

The copyfitting will probably need to add minimum and maximum to all
properties that could be used, you're right.  There are a lot of details
not yet worked out.
