XPath syntax problem when importing an XML-Schema [message #420734]

Hi,

I have got the following error message probably due to an unaccepted Xpath
syntax

when i try to create a new EMF Model starting from the XML-Schema below.

I use Eclipse 3.4, and EMF version 2.4.0.

Error Message :

"Problems were detected when validating and converting the XMLSchemas"

Error : XSD : the value xtce:TelemetryMetaData/ParameterTypeSet/* |
xtce:CommandMetaData/ParameterTypeSet/* of attribute xpath must conform to
pattern '(\. ......

This XML-Schema is considered as valid by XMLSpy and corresponds to an
OMG/SDTF standard (see :
http://www.omg.org/spec/XTCE/20061101/06-11-06.xsd)

Thank You for any help,

Best Regards

Erwann.

The XSD model is strictly validating the regular expression provided in
XMLSchema.xsd and that regular expression doesn't not permit spaces in
the xpath expression. I'm not sure if there have been any errata about
that issue, but the regular expression in the normative schema for
schemas hasn't changed so strictly speaking, an xpath with spaces
doesn't conform to what's specified in the normative schema for schemas,
so until that W3C changes that regular expression, it's best to avoid
the spaces. I've pointed out many times that XMLSpy not reporting
problems isn't the best indication of there not being problems. You can
simply ignore this error since EMF doesn't do anything with the identity
constraints anyway even if they are well formed.
