The HTML version of every tag that we accept.

Alias =

NOTE: We only attach to the regenerator if you are using digested

assets, otherwise we forego any association with it so that we keep
your builds ultra fast, this is ideal in dev.  Disable digests and
let us process independent so the entire site isn't regenerated
because of a single asset change.
