custom xml data type

When I try to create a custom xml datatype I get the following error:
CREATE TYPE myOwnXMLType FROM xml;
Msg 15226, Level 16, State 1, Line 1
Cannot create user defined types from an XML datatype.
Is there anything I can do ? Other types work fine (int, nvarchar(max)
etc.). I use SQL Server 2005 Standard Edition.Alex Voit wrote:

The documentation lists the following allowed base types:
bigint
binary(n)
bit
char(n)
datetime
decimal
float
image
int
money
nchar(n)
ntext
numeric
nvarchar(n | max)
real
smalldatetime
smallint
smallmoney
sql_variant
text
tinyint
uniqueidentifier
varbinary(n | max)
varchar(n | max)
The xml data type is not listed as an allowed base type for CREATE TYPE
FROM.

that you need.
