For anyone interested:  Recent updates based on a number of kind discussions here and elsewhere:

 

*  Anonymous element tags  <[  and ]>  are sugar for element tags with empty strings as name: <""> and </"">

*  Date intervals, wildcarding and approximation from modern ISO 8601:2018

*  Limit on token lengths to support SIMD processing of tokens better, such as Unicode Normalization filtering

*  Section on positioning

*  More examples

* Grammars reworked to show how fragment tags can be identified throughout document using regex:    

      .*(<<.+>>.*)*

    and how all tags can be identified throughout document using regex:

    \s*((<.+>[>]?).*)*

  (The revenge of the Desparate Perl Hacker?)

So I have rejigged the ideas based on many comments here, given it a name, and I have put up a little page, with much clearer examples.

I think it hangs together OK.
