And why use XML in a browser based solution ? this is yesterday technology
XML is fantastic to webservices, but slow in a browser where todays
dataformat
is JSON that goes directly into Javascript objects without any passing.

since the 5250 data stream is probably stable and not being enhanced

Well that to a degree was what they were originally going to do with
Open Access but (thankfully) were talked out of it because it simply
added overhead with no benefits. Anyone can write an OA handler that
"wraps" the OA delivered data in XML if they want/need it - but as
Profound, Look and VAI have proved XML is not needed.

A 5250 stream delivered as XML is already available in Zend Bridge -
that is how it works and I suspect the additional overhead of the XML
is what slows it down some - although I confess I haven't given it a
test drive on Zend Server.
