Schema validation failure in wM 7.1 but works in 6.5

We have transfered the packages from wM 6.5 to wM 7.1.
The same xml is working fine in wM 6.5 but failing at pub.schema:validate in wM 7.1 with the following error: java.lang.Exception: INVALID
List of errors:
[0] pathName=/RootElement errorCode=NV-003 errorMessage=[ISC.0082.9003] Unable to locate a matching element declaration
at pub.schema.validate(
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

  1. Are there any changes that we need to do make this validation work?
  2. validation is done based on the schema. So I want to generate xsd from wM schema and validate this xml using
    xml spy. How can I generate the xsd file from the wM schema?

Significant updates were made to IS XML Schema support in 7.1. Read the release notes carefully for details.

Best practice is to start with an XSD, create an IS schema from that XSD and validate documents against the IS schema. I have not found creation of XSD from IS doc types or schemas to be reliable.


But what if we don’t have the xsds available? Is there any other way to create the xsd from IS schema?

What are the other steps that need to be followed to solve this, assuming that we don’t have xsds?

We are facing the same issue in our 7.1. Have you found a fix for this?
