I think it would make sense to have the respective XSLT in this project. After all, a PR requesting a change would typically involve changes to:

• the documentation
• the ontologies
• this xslt

@gsautter, what do think about moving the XSLT that converts gg-xml to rdf/xml into this repo?

[gsautter]

We sure could do that ... maybe not as the primary source, but definitely as a copy ... might have to do some cleanup beforehand, though ...

@gsautter, could you please link to the location of this XSLT? The changes done there need to be reflected in synospecies for it to be working again.
