Topic: CCDA Logical Model Type Representation

In the logical models for CCDA some elements are defined with ElementDefinition.representation = typeAttr. Even if the element has a fixed type and doesn't have an xsi:type attribute in the instance. An example would be Observation.code. Is is an error in the StructureDefintion or is this just special to CCDA? @Oliver Egger

I don't know the CCDA logical model but In CDA xsi:type can also be specified even if there is a fixed type (xsi:type may be used at other times according to the XML Schema specification.). The CDA Logical Model has added for this reason also typeAttr on Observation.code. Does this solve your question?

Ah I see, thanks. I found it in the specification. Strange, but ok :D

I'm currently trying to make these StructureDefinitions work in the C# API. Any chance to add elementdefinition-defaulttype (http://hl7.org/fhir/StructureDefinition/elementdefinition-defaulttype) officially as a core extension? Would be nice to have a proper definition for it
