Indeed, I am in process of developing a schema language in which the
only allowed content models are of this form:

model1 = elementa | elementb | elementc ...
model2 = elementa | elementd | ...
elementa = element elementa {model1 | ...}*
elementb = element elementb {model2 | text | ...}*

I.e., a named model is a choice between named elements, and a
named element contains an optional choice group involving named models
and possibly #PCDATA.

What's the point?  That will appear.

And through this revolting graveyard of the universe the muffled, maddening
beating of drums, and thin, monotonous whine of blasphemous flutes from
inconceivable, unlighted chambers beyond Time; the detestable pounding
and piping whereunto dance slowly, awkwardly, and absurdly the gigantic
tenebrous ultimate gods --  the blind, voiceless, mindless gargoyles whose soul
is Nyarlathotep. (Lovecraft) John Cowan|jcowan@r...|ccil.org/~cowan
