Re: [mdht-dev] xsi:type problem in observationMedia/value

[Tony Schaller <tony.schaller@xxxxxxxxxxxx>]

Hi Sean

In fact you are right, the xsi:type is not missing.
But unfortunately the German "Arztbrief" Schematron rules are requiring it:

<iso:pattern name="OMVL observationMedia Class">
	<iso:rule context="cda:observationMedia">
		<iso:assert test="cda:value/@xsi:type='ED'">
			vhitg-ruleset.ent: <emph>observationMedia</emph> must contain a value of type ED.
		</iso:assert>
	</iso:rule>
</iso:pattern>

Regards,
Tony

Betreff: Re: [mdht-dev] xsi:type problem in observationMedia/value

Hello 
	The underlying schema has the value defined as an ED (as compared to other observations where it is a ANY) and as such the xsi:type for the value is not required; So the "xsi:type="ED" is not in fact missing 

	If you can be a bit more specific as to why you need to have the xsi:type might be helpful

	In the meantime - there are some options and none particular simple or straightforward as far as i can tell First is to look into the EMF serialization - there might be some way to force the xsi:type;  Second is to modify the cda ecore model and regenerate the code You would change the observation media value to an ANY then when you set the ED it will also set the xsi:type

	Again - I want to reiterate that in this case the xsi:type is completely superfluous 

Hope this helps 

Thanks for your interest in MDHT

Sean
