As a follow-up to this, here are my scribblings from the C14N
1.1 discussion:

- xml:base with relative URLs can actually change meaning when
  subject to the current c14n algorithm; the right algorithm
  would have to go up the ancestor axis and concatenate things
  appropriately.
  
  (This has been discussed in more depth on the list in the
  meantime.)
  
- For xml:id, we have the "moving attributes around" attacks.

- For xml:space and xml:lang, the current algorithm behaves
  correctly.

- id checking (which is a SHOULD in xml:id) should become a
  MUST when xml:id is used in a c14n context.
  
- non-xml:id ID attributes rely on external schemas for
  validation

- XPath does not include uniqueness checking

I hope these help.

At the same time, regrets for both Jose and myself for this
Wednesday's call; we'll both be at a workshop in New York this
week.
