Can you guys show me an example of how this is used in the xml file?

The only drawback is that there is no way to validate whether the input has the dbkey attribute as a parameter (can you suggest a way to validate?). Attached are the diff's to the current version in galaxy-central. See Dan's recent commit for validation via data tables: https://bitbucket.org/galaxy/galaxy-central/changeset/150069a23aad Thanks, J.
