I made the mistake of reading this specification today.  Allow me to list
the faults:

    1) uses probably the most difficult syntax to parse of all options:
       balanced quotes inside balanced parens with encapsulated functions
       and concatenated schemes;

    2) frequent use of characters that are explicitly disallowed
       in the URI syntax and thus must be escaped;

    3) calls itself a "scheme" and encourages the naming of new "schemes"
       for fragment syntax, in spite of the fact that the URI syntax
       already has something called a scheme; (doesn't anyone have a
       thesaurus?)

    4) focuses on mechanical identification of XML elements (fragile
       and media-type-specific) rather than the content (section heading,
       paragraph number, paragraph text, etc.).

In short, these things are not suitable for use with URIs and should
not be recommended by the W3C.
