libxml2 is weird like that :) . You just have to live with it.

(Perhaps libxml2 is set up like this to be source-compatible= with libxml1, so programs which e.g. #include <libxml/SAX.h> can be = compiled without modifying the source, just by adding an extra compiler swi= tch. But I'm just speculating.)

To be clear, you're talking about this XSD extension datatype? https://www.w3.org/TR/xsd-precisionDecimal/ Technically, this document specifies an extension to XSD 1.1 while libxml2 only supports version 1.0. But since it's just a new datatype, it should work with the old version as well. > Is this something that you would be interested in? Me personally, no. But libxml2 is an open-source project, and in principle we accept contributions from everyone. Things can move a bit slow due to a lack of maintainers, though. Nick
