Good catch.  I'm not sure I meant deserialization, because whatever the 
box does, it has to put something back on the wire, unless it has shared 
memory with the main application system.  Frankly, the crept into my note 
because in our writeups of our XML Screamer project, the phrase "parsing, 
validation and deserialization" appears a lot.  Here, I mean't something 
more along the lines of: parsing, validaiton, transformation, signature 
checking, etc.

As to what goes back on the wire, it's an issue in any case, and I think 
there are different answers for different boxes.  In some cases, where the 
point is more transformation or signature checking, I think the answer is 
that what goes on the wire is plain old text XML, but that XML may have 
been transformed, decrypted and signature-checked, so it's much more 
"ready to go" when received by the main computer.  I think some systems 
may use proprietary binary formats, but I'm not sure about that.  Again, 
none of this should be taken as a statement about IBM's Datapower products 
in particular:  Rich Salz can answer questions about them.

Just curious: If XML Gateways are used for 'deserialization', what is 
the textual XML representation deserialized to? I can't seem to think 
of any reasonable option.

Thanks,
