## #4308 — Timm Friebe — 2003-08-31T10:09:51+00:00

Hello,

as ext/sablot has been removed from CVS [1], I would like to make a
feature request. One of the features I really liked about Sablotron was
the possibility of using schema handlers [2] to be able to realize
callbacks to PHP while processing (I used it to calculate image sizes if
needed, to retrieve "include"-snippets from a database and to track
dependencies). AFAIS, there is no such feature in th current ext/xsl
(correct me if I'm wrong), but after looking at some of libxml2's
documentation, I guess it would be possible [3].

Is someone already thinking of implementing this?
