I have at least two concerns with your scheme and examples:
  - Why the word number approach to refer to elements, when HTML and XML 
has a well defined method of creating a relationship between data. Why 
don't you just enclose the data you want to mark up in a tag? It's what 
they're there for after all, and people _and_ tools already knows how to 
deal with that.
  - It isn't well formed XML or HTML. Given the number of tools that 
speak XML/HTML it would be significantly easier to work with this scheme 
if it was. Have you looked at RDF/A for instance as an alternative? (See 
http://www.formsplayer.com/notes/rdf-a.html). Why take this shortcut? It 
would force people to use custom parsers to deal with it.
