Jaxb2 is very simple, generates nice pojos (this is not the case with
xmlbeans) and afaik, both handles unspecified extensions to schemas...
Or even a stax based parsing would be great (sax is such a nightmare
compared to pull parsing..).
JAXB v2 wasn't available (with a suitable license) when we were
originally working on PXE, so that was ruled out.
StAX parsing won't permit schema validation, so that's a no-go there.
And schema validation isn't truly enough, as there are valid but
illegal BPEL processes.
Tatu Saloranta has a schema validator for StAX I believe. And I think if
JAXB was used it will ensure that the xml conforms to the schema. Also
JAXB can capture the additional elements via a getAny() accessor. As you
point out, post validation is needed in addition and I think this could
be done just as easily with jaxb as something else.
