[xml/sgml-pkgs] Bug#832602: [libxml2] Schema validation with attribute checks fails (upstream #766834)

[Mònica Ramírez Arceda]

Hi,

This bug is affecting xmlstarlet (see RC bug #832864). I could disable
two tests to make xmlstaret build but I would prefer not to do it. Are
you planning to fix it before freeze date (2017 Feb 5)?

Thanks!
