SAX, Java, and Namespaces (was Re: Restricted Namespaces forXML)

[Borden, Jonathan]

Healthcare applications have the same issues as other applictions, with the
added 'benefit' of multiple standards issuers and third party 'interested'
organizations.

For example elements from the

hl7: namespace
dicom: namespace
hicfa: namespace

might be combined in a single document.

Namespaces aren't that difficult to deal with for the developer, but need to
be dealt with by organizations with are developing DTD's,Schemas etc which
span standards.

Now, getting the U.S. and U.K. to agree on a set of standards (and
namespaces) is its own issue :-) This is where XML and XTL has potential,

e.g. U.S. HL7 2.3 <->  HL7/XML transport <-  XTL -> U.K. EDIFACT XML
transport <-> EDIFACT

Transformations expressed in XSL/XTL can assist with interface of different
messaging systems and integration of different 'flavors' of HL7.
