Hibernate version: 3.05

Given a hibernate-config.xml with several 1-per-class mapping files named as <mapping> elements, suppose I want to use schema generation, for all but one of the named mapping files (let's say that this mapping is to a legacy table and all the rest are new). Is there a convenient way to specify in the mapping files that DDL for this one table should not be generated when schema generation is run? Or must I manually remove this from the generated ddl (or comment it out of the hibernate-config)?
