Database-first convert-mapping to XML fails to add length to varchar primary key in id tag

In using orm:convert-mapping xml --from-database the xml that is generated for varchar columns does not receive a length attribute.

Therefore - orm:validate-schema fails and the schema tool reports that the column must change to a varchar(255) when it should be just fine with the varchar that was already there (ex. varchar(10)).

Note: I discovered this on composite keys - unsure whether this is for all or only composite.
