If you're interested in static validation of db/dbd files, you might
have a look at my 'dbdlint' script.  This can either validate individual
files for basic syntax (--partial), or a full database w/ recordtype
defs (--full).

This includes a handy (to me) feature to detect unintentional "external"
links (aka typos).
