All:
Following our conversation yesterday I created a model in WTX which does
what I believe we were trying to do here. The first set of testdata
is good (and hence not much fun!). The second set of testdata is
bad but is 'directed' through the choices appropriately with the discriminators.
Hope this helps explain how these look
in WTX.
Here is Mike’s discriminator1
case in WTX,
Trying to keep it as simple as
possible but here is the tree for the easiest modeling:
The two ‘identifiers are circled
in RED.
With good data – this is what
the trace looks like: (notes are in RED
as well)
C1(a 10)(q 20)
X5(b 62 JQ6)(b 47 H)

Now the bad data – let’s see
how that flows. In this case we want to discriminate that the data is an
a and therefore an L Record (without looking at b’s or S Records). But
as we have an invalid L record at the Top choice we want to go to blob
as we have no discrimination at that level.

Attached are two files. One is a DFDL schema that uses
discriminators. The other is a test case file.
I'd like to review the issues with discriminators on our
call tomorrow by walking through these examples.
To do this we will absolutely have to have screen sharing
going on so I can point at things.
So I have setup a "gotomeeting" which is a low
impact web screen sharing thingy.
If you've not used gotomeeting before, there is a brief
download required, so you might want to get this out of the way before
our call.
