[Responding to a question posted to XML-DEV]

There are (at least) two standards organizations developing XML DTDs for healthcare information, the ASTM's XML Healthcare subcommittee (http://www.astm.org) and HL7 (http://www.hl7.org). These standards efforts are being coordinated using an interoperable clinical header. HL7 has traditionally focussed on interapplication messaging protocols whereas ASTM has traditionally focused on documentation.

The ASTM architecture defines a common clinical document format containing a clinical header and body. The body content models generally specify text (#PCDATA), XHTML Basic content (%Flow.mix) or reference external documents using XLinks.

http://www.openhealth.org/ASTM/ contains a number of documents and DTDs related to the recent E31.25 draft ballot. The XChart application implements the 2001-2-18 draft ballot ASTM standard internally (though the web based demo displays documents as XHTML) -- this is to be released as open source once we can package the 2001-2-18 mods for distribution.

We expect that future versions of this standard will specify XML Schema -- which is what you did ask about -- as well as other *standardized* schemata.
