[tei-council] Mode attribute for <classes>

[Lou Burnard]

for the record, here's what I think we just agreed to investigate

1. Allow @mode on memberOf (the @key value acts as its unique identifier 
since within a single Spec, you can't be a member of the same class more 
than once)

2. Interpret @mode values on memberOf as follows

  not specified means mode=add
  add : means make this element a member of the class nominated if it 
isn't already and raise an error if it is
  change: doesn't mean anything so should probably raise an error
  delete : means remove this element from the class nominated if it is a 
member of it already and raise an error if it is not
