T-SQL: Change Schema of User Defined Type

I've been working with one of our developers to try and rationalise some database objects into some sensible schemas using the ALTER SCHEMA syntax:

http://msdn.microsoft.com/en-us/library/ms173423.aspx

Just out of interest, is it me or is this syntax for changing an objects schema a bit strange? Are you altering the Schema or the Object? Anyhow, I digress...

In our example, we have several User Defined Types which require transfer. Here is some sample code illustrating the problem:

CREATE SCHEMA NewSchema
GO
CREATE SCHEMA OldSchema
GO
CREATE TYPE OldSchema.MyUDT FROM VARCHAR(20);
GO
ALTER SCHEMA NewSchema TRANSFER OldSchema.MyUDT
GO


This gives the rather unhelpful error:

Cannot find the object 'MyUDT', because it does not exist or you do not have permission.

I checked the documentation and there isn't anything that suggests types should be treated any differently so I was stumped. Fortunately, I managed to unearth this post which provides a workaround to the problem.

ALTER SCHEMA NewSchema TRANSFER type::OldSchema.MyUDT
GO


I'm not sure why this is not documented in Books Online (or at least nowhere I can see). One to keep an eye out for.
