Undeclared Tag Error in SQL

[Jason Sauer]

We use "FOR XML EXPLICIT" and "OPENXML" heavily on our SQL 2000
server. Every now and then we get an "Undeclared Tag ID" error (SQL Error
#6806). If I open the stored procedure, modify it in any way (add a carriage
return, hit the space key) and save it, the error goes away. To my knowledge
we are current on service packs.

We are starting to get the error a few times a day in different stored
procedures.
Has anyone else had this problem and better still, does anyone know how to
fix it?

Any help would be greatly appreciated.

Thanks!
