The Skotos StoryBuilder library does something similar, though it does
not have a strict DGD. For instance, here is the XML of a real (but
simple) object:

pritchel hole (for punching out pieces of iron).

However, we can also break this up smaller, for instance, the detail
above called "surface" can also be XML'ized as:

</context>

<Base:Description type="brief">

<Base:Description type="examine">

Or the description examine can be XML'ized:
<object id="OBJ(Ur:tool:smith:anvil)">
<context>
<iterator var="id" val="surface" type="lpc_str"/>
<iterator var="type" val="examine" type="xml_pcdata"/>
</context>
<Base:Description type="examine">
The waist-high upper surface of the anvil is smooth and dark. There
are two holes in it: a square hardy hole, and a round pritchel hole.
</Base:Description>
</object>
Theoretically (though never done in practice) we could convert a whole
game into a single XML file.
