[oXygen-user] Confusing Message When Schema Cannot Be Found

[Sorin Ristache]

Hello,

It is a generic error message reported when a schema is not 
associated with the XML document using any of the 
association mechanisms supported in oXygen including the 
xsi:noNamespaceSchemaLocation attribute. An XML parser does 
not report such a detailed cause of the error (the attribute 
xsi:noNamespaceSchemaLocation was not spelled correctly, the 
URI specified as the value of the attribute could not be 
resolved using a URI resolver, etc).

As you can see there are possible resolutions of the error 
in the error message itself and for a more advanced 
association mechanism like an XML catalog oXygen provides a 
special debugging method: the logging output of the XML 
catalog based entity/URI resolver which you can enable from 
menu Options -> Preferences -> XML -> XML Catalog -- Verbosity.


Regards,
Sorin
