References to XML Schema Specification

The same as in editing XML documents, the message of an error obtained by validation of an XML Schema document includes a reference to the W3C specification for XML Schema. An error message contains an Info field that will open the browser on the "XML Schema Part 1:Structures" specification at exactly the point where the error is described, thus allowing you to understand the reason for that error.

Link to Specification for XML Schema Errors

Validation of an XML Schema containing a type definition with a minOccurs or maxOccurs attribute having a value larger than 256 limits the value to 256 and issues a warning about this restriction in the Message panel at the bottom of the Oxygen XML Developer plugin window. Otherwise, for large values of the minOccurs and maxOccurs attributes, the validator fails with an OutOfMemory error that might make Oxygen XML Developer plugin unusable without restarting the entire application.

Important

If the schema imports only a namespace without specifying the schema location and a catalog is set up to map the namespace to a certain location, both validation and the schema components will correctly identify the imported schema.
