REF_I12 in V2.XML 2.4
You must manually change the following code in the REF_I12 schema in V2.XML 2.4 after running the Update2XMLSchema tool:
<xsd:element ref="REF_I12.PATIENT_VISIT" minOccurs="0" maxOccurs="1" />
<xsd:element ref="REF_I12.PATIENT_VISIT" minOccurs="0" maxOccurs="1" />
You must replace the above code with the following, in order to fix the ambiguity caused by multiple occurrences of the REF element definition:
<xsd:element minOccurs="0" maxOccurs="2" ref="REF_I12.PATIENT_VISIT" />
