refentry.meta.get.quietly — Suppress notes and warnings when gathering refentry metadata?
If zero (the default), notes and warnings about “missing” markup are generated during gathering of refentry metadata. If non-zero, the metadata is gathered “quietly” -- that is, the notes and warnings are suppressed.
If you are processing a large amount of refentry
content, you may be able to speed up processing significantly by
setting a non-zero value for
refentry.meta.get.quietly.
