Glade 2.0 DTD patch for accessibility

[Bill Haneman <bill haneman sun com>]

Hi all:

The glade-2.0 dtd from libglade HEAD includes initial support for 
accessibility properties.  I attach (inline) a patch that I believe 
will extend this to provide the level of accessibility support which 
we need for Gnome 2.0.

Note that the <accessibility> element has <atkproperty> children 
rather than <property> children:  this is because some atk properties 
are themselves atkobjects, and thus can't easily be specified using 
#CDATA.  Also <atkaction> and <atkrelation> are subelements and not 
properties, since there may be multiple instances of <atkaction> and 
<atkrelation> associated with an <accessibility> element.  

If this patch is acceptable, I am willing to take responsibility for
seeing that the necessary code is added to libglade to parse the 
<atkproperty> elements and call the appropriate ATK API.

Thanks,

Bill
