Looks like you do not have the right files. I just downloaded those files and I was able to validate them in Eclipse and XMLSpy but the schema import in to WM still fails.
I went through all the schemas and looks like the fpml-doc-5-3.xsd has some references to attributes that are not defined in the schema.
Search for this in fpml-doc-5-3.xsd
<xsd:group name=“Validation.model” fpml-annotation:deprecated=“true” fpml-annotation:deprecatedReason=“Replaced by Implementation Specification in msg header”>
replace it with this line
<xsd:group name=“Validation.model”>
I was able to import the modified schema into WM developer. I would strongly advise open a ticket with FPML and get an official version of the schema with out the orphaned attributes.
Cheers,
