Meaning the hook get transformed the contract not. BTW the TEST is not
allowed in this position.

Please try requesting:
http://localhost:8888/resolve.contract.html.language-variants or AFAIR
for your case
http://localhost:8889/resolve.contract.html.language-variants Does the
contract show up?
If not, does {lm:themer.project.dir} point to the dir? What does
http://localhost:8888/ls.contracts.project.html return? Is the contract
listed?

The contract looks alright. The only thing that you define in the usage
<forrest:contract name="language-variants"
dataURI="cocoon://#{$getRequest}.languages.xml"/> and in your structurer
<forrest:contract name="language-variants" />. That should not matter
ATM for the testing but later on you may want to change this in the
structurer.

Please report back when you tested the above links and tell us what the
outcome is.
