[DFDL-WG] DFDL Discriminators discussion

[Alan Powell]

Following on from Stephanie's WTX example on last weeks call I think that 
restricting discriminator to resolving their parents provides the level of 
control that we need.

I have updated Mike's example with this syntax 


Note I have flattened the schema as I find that easier to read and 
'enhanced' some the the dfdl properties.

To illustrate the flexibility if  'L' had a test="{ fn:exists( . ) }" 
discriminator then if an L record had been found then the parse would fail 
rather than backtracking to Blob.
