Not enough? Why? explain these please? What's the impact of wrong choice?
When to 'break' this rule (guidance)

Wozzat?
  Template match? Never heard of it.
  Descent... of what? Why default? alternatives?

    What, how does xpath help / cause problems?
    How used in this funny 'language'
     The real nugget of XSLT, but quite alien to procedural programmers?

  Yep, at last, something  most will recognise recognise!
  But where is my 'repeat until'?

     I'd split
        Rearranging and repeating things, again quite key (why etc...)
   variables? Oh no they're not.
       (hope apply templates explained before now)
       BIG session on select 'rules'
       modes? Another foreign language.

Thanks Rick.
