Please evaluate, it looks to me that the module/classes doesn't exist any more.

Comment 3 Svata Dedic 2013-06-05 13:21:33 UTC

It does, but in the contrib repository; xml.schema.abe module

Comment 4 Martin Balin 2016-07-07 09:56:34 UTC

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
