If I write a page named Bar with the text

------------------
Some text [[test relation := Foo]]
[[Foo]]
------------------

I get the link to the page Foo in the second case but not in the first.
If y write a page named Attribute:Test_relation whith the text

-------------------
[[has type::Type:Page]]
-------------------

in the factbox of the Bar page I get "[Oops! Unsupported type "Page" defined for attribute]" even if I cut and paste the content of "Type:Page" from ontoworld.org

any idea of what I have to do to correct this problem?
