How to convert JspxIncludePathReferenceProvider for IntelliJ IDEA 8

I wrote an IntelliJ IDEA plugin for version 7.0 that uses JspxIncludePathReferenceProvider to enable autocomplete in a custom JSP tag (eg dsp: include src = "/path/to/file.jsp").

New version 8 IntelliJ has changed the API for link providers and I can't figure out how to convert this plugin to the new API.

Any suggestions?
