What well-formedness errors are possible in a synthetic Infoset?
The only ones I can spot are:

    + duplicated attribute names on an element
    + processing instructions whose [content] property contains
      a PIC delimiter (?>)
    + comments containing a COM delimiter (--)
    + illegal characters in element and attribute names
      (this one is questionable)
    + countless namespace pathologies

Are there any others?

I really don't believe the first four items are worth getting
worked up over.  The last one (namespace pathologies) is the only
serious problem.
