Error converting nvarchar(max) in table-type

Hi,

I get the error "Cannot understand      ` [Test1] [nvarchar](max) NULL`" when trying to convert this user defined table type:
```
CREATE TYPE [dbo].[UDT_Test] AS TABLE(
	[Test1] [nvarchar](max) NULL
)
```

The nvarchar(max) seems to be handled in normal tables, but not in table types. Can you please help?

regards,
Tamas
