Jing: »first occurrence of ID "some"« is reported for all non-first instances about focheck

[tgraham-antenna]

focheck uses Jing for ID and IDREF checking rather than using Schematron on the theory that Jing should be faster because the checking is built into the validator.

The only way to change the Jing error messages would be to override the messages file, but getting rid of the 'first occurrence of ID "some"' messages would require modifying Jing and getting oXygen to use the modified Jing. Both are doable, but both are more work for the user than just installing an add-on.

One day, I'll find time to check whether using Jing or using an xsl:key with the Schematron is faster for ID and IDREF checking.
