To benefit of this PR on vscode-xml, the PR redhat-developer/vscode-xml#782 should be used and merged.

This PR provides the capability to:

• report XML syntax validation for *.exsd files
• don't report XSD validation for *.exsd files.

Given this test.exsd file:

<schema xmlns="http://www.w3.org/2001/XMLSchema">
   <annotation>
      <appInfo>
      </appInfo>
   </annotation>
</schema>

You should see no error., If you rename the file with test.xsd, you should see the XSD error:

It means *.exsd file don't report some XSD error, but it should report XML syntax error, to test that update the test.exsd with this content:

<schema xmlns="http://www.w3.org/2001/XMLSchema">
   <annotation>
</schema>

You should see the following error:

If I add a <?xml-model...?> processing instruction, schema-related errors are still reported in .exsd files

[angelozerr]

If I add a processing instruction, schema-related errors are still reported in .exsd files

Could we see that in an another PR please. The main goal today is to have a support of *.exsd files in Eclipse IDE, and xml-model is never used in *.exsd files.

Works well for me.
