Hi Alan,

Thanks for your reply. The Forms WG discussed this today [1], and while we  
agree with point one, about relaxing the restrictions on method, we  
realise that there is still some design work to be done on part two, and  
we see close parallels with some serialisation work we have recently been  
doing.

So we are going to think about possible solutions over the next two weeks,  
and then discuss them (please free welcome to chime in).

However, we don't want to this issue to block us going to last call, so if  
we should fail to solve it properly before going to last call, we will  
take your issue as a last-call comment, so that it doesn't get lost.

Best wishes,

Steven Pemberton
