We are attempting to exchange HL7 2.7.1 messages using the XML Encoding Syntax, Release 2 specification. Some of those messages contain escape sequences in the OBX-5 field. However the HL7 Version 2.7.1 Messaging Schemas don't define the <escape> element anywhere. And the "OBX.5.CONTENT" type isn't defined as mixed. This is causing schema validation to fail on our message XML documents.
Is this a defect in the schema? It doesn't appear to match the written specification. Do we need to customize the schema to make it work or has anyone found another solution?
Definitely a defect in the schema. You'll have to customize it to make it work
