In my view:

XML (or any other Tag-language) will be used to express:
- Datamodels of a part of the universe, which handle the relationships
between entities with the Model. It defines the Context of the information.
- with Terminology (a set of Tags) which give names to the entities
- with  Rules to obey.

It will be likely that the above examples will be Tagged like:
<blah>  <number> 1234 </number> </blah>  if rules of the model allow it
allow it.
<blah>  <ASCII> 1234 </ASCII> <blah>

<blah> will be an entity from a Model indicating a context
<number> will be an atribute indicating how things are coded

Attributes will be derived from other Models.

'Nothing to markup' is nothing.

It equals chaos.
