This resolves my comment. Thank you.

In that case I suggest that this is explicitly mentioned in the primer, since users are likely to mix up the different syntaxes (like I do...). A note with your above wording would make this clearer:

[[
Turtle (as opposed to N3) does not define ':' to mean the current document.  If a user of Turtle wishes to use : in that way, they would need to add the prefix directive "@prefix : <#>." to their document. Unlike N3, Turtle does not define any "default" prefixes.
]]

Some text on how to refer to the current document would be helpful as well.

Thanks,

Lars
