Describe the bug
The example XMLs in the aforementioned page don't reference the suppression XSD correctly.

Expected behavior
The XSD should be used by XML editors to validate the given schema. For that the XSD needs to be referenced correctly. An example of a correct reference can be found in https://www.ibm.com/developerworks/library/x-tipsch/index.html#gettingdown.

Additional context
Basically each schema is referenced via a namespace. The example XMLs https://jeremylong.github.io/DependencyCheck/general/suppression.html currently only define a namespace but not the underlying schema.
