sp_repladdcolumn does not allow adding columns of datatypes that are new to this release.

Hello,

When I try to add a column to published database I get this below error

Msg 25014, Level 16, State 1, Procedure sp_repladdcolumn, Line 378
sp_repladdcolumn does not allow adding columns of datatypes that are new to this release.

Version: SQL 2005 9.0.5000

Database compatiblity:90

Command:sp_repladdcolumn 'STOCK', 'UDe1', 'XML', 'all', null, 0, 0

 This commands seems to have worked on different server. Not sure why I get this strange error. 

Any suggestion is appreciated.

Thanks

Suresh
