The problem seems to have been that I was modifying the newly created
LexicalBlock after creation. Not sure why. I suppose something was
caching it? But I'm not sure.

I've changed it so that the lexical block is created with the
appropriate discriminator value. This seems to work. I still don't
seem to be picking up discriminators from the binary. But I'm not sure
if it's a problem with the reader or they are not being written down.
How can I check that?


Thanks. Diego.
