[xml/sgml-pkgs] Bug#749198: libxml2: incorrect Relax NG parser error with included grammar

[Vincent Lefevre]

Package: libxml2
Version: 2.9.1+dfsg1-3
Severity: normal
Forwarded: https://bugzilla.gnome.org/show_bug.cgi?id=730705

Relax NG is broken: I get an Relax NG parser error on correct .rng files.
I've attached a testcase.

$ xmllint --relaxng test1.rng test.xml
test1.rng:3: element include: Relax-NG parser error : xmlRelaxNG: include docbook.rng has a define subscript but not the included grammar
dbpoolx.rng:10078: element define: Relax-NG parser error : Some defines for subscript needs the combine attribute
Relax-NG schema test1.rng failed to compile
<?xml version="1.0"?>
<para>test</para>

But if I replaced the <include href="dbpoolx.rng"/> in docbook.rng
by the referenced file (with the needed changes such as removing
the grammar element), the error disappears:

$ xmllint --relaxng test2.rng test.xml
<?xml version="1.0"?>
<para>test</para>
test.xml validates

This issue is similar to:

  https://mail.gnome.org/archives/xml/2003-March/msg00037.html

but the testcase on this page works fine with this libxml2 version.
