Possible problem in the schema? about ids

xs namespace is is defined in the header of the XSD.
XML Spy, Notepad++ and Eclipse have no issues.

That wasn't the question. My concern is about the ref attribute of the xs:element.

XML Spy, Notepad++ and Eclipse have no issues.

Neither has Sublime Text. However, I am uncertain that any of these tools also check that the content of the schema (not its syntax) is correct.

I did some additional digging here:

xs:restriction is a built-in data type of the namespace xs, right? Therefore it should be type and not ref in my opinion.

@berlotti I request to reopen the issue.
