Derivation Depth?

[twcook]

Is there a limit to derivation levels in XML Schema 1.1?
I get this error:

E [Xerces] rcase-NameAndTypeOK.7: The type of element 'definition', 'ct_013f4560_9b34_4081_9162_e58245cec514', is not derived from the type of the base element, 'DefinitionType'.

When in fact ct_013f4560_9b34_4081_9162_e58245cec514 is a restriction of SlotType which is an extension of ItemType which is an extension of DefinitionType.

Thanks in advance.

After setting the parser to Saxon EE and version to 1.1; this problem disappeared.

Thanks.

Hi,

I'm glad you have sorted out this problem.

This could be something that we should test against Xerces and report it to the Xerces project.

Could you please send us your schema hierarchy (or a sample of it or even a description) where you reproduced this problem? If possible, please send it to support AT oxygenxml DOT com.

Regards,
Adrian
