Thanks for looking at it!

Yeah, I looked at that but wasn't sure what to do with it. We should
have validated the decl header when the XML value was created, so if
we get here then either the value got corrupted on-disk or in-transit,
or something forgot to do that validation, or libxml has changed its
mind since then about what's a valid decl. At least some of those
cases are probably legitimately called INTERNAL_ERROR. I thought for
awhile about ERRCODE_DATA_CORRUPTED, but I'm not convinced that's a
better fit.
