Wouldn't a function g_markup_collect_attributes_ignore_unknown() be a
viable solution as well?

Hello,
In DBus introspection XML files we write by hand, we use XML
namespaces to put in various additional bits of information.
Something very similar is done in the Telepathy project. It looks
like this:
http://cgit.freedesktop.org/telepathy/telepathy-idle/tree/extensions/Connection_Interface_Renaming.xml
Now, it turns out Glib DBus introspection code fails in the presence
of XML namespaces. The error I am getting from
g_dbus_node_info_new_for_xml() is:
attribute 'xmlns:ns' invalid for element 'node'
The code in question is in gio/gdbusintrospection.c, but the error
comes from g_markup_collect_attributes() in glib/gmarkup.c. It's not
that GMarkup can't parse attributes with colon in the name, it's just
that g_markup_collect_attributes() treats the presence of extra
arguments besides those being requested as an error. That behaviour
is not configurable.
So, I've got two options at this point. I can either write my own
introspection XML parsing code or I can modify Glib code to ignore
any unexpected attributes. I don't mean modifying the behaviour of
g_markup_collect_attributes() but rather stopping using it in
gdbusintrospection.c.
My question is, would such a change be acceptable for inclusion into
Glib?
