`xsd:anyURI` not recognised

[SkypLabs]

When I use the rules below to import axioms from a spreadsheet, I get the following error message:

Individual: @B* Types: Company ... Facts: hasAsWebsite @G*(xsd:anyURI)

However, if I replace xsd:anyURI by xsd:string, it works.

I'm using Protege v5.1.0 and Cellfie plug-in v2.1.0.

Any idea why?

I just figured out that xsd:anyURI is currently not supported: https://github.com/protegeproject/mapping-master/wiki/MappingMasterDSL#literals.

Any plan to add it in the future? Also, it would be nice to have a more specific error message.
