Github user HansBrende commented on the issue:
https://github.com/apache/any23/pull/104
`Current XML parsers can use both lang or xml:lang, but since librdfa uses
an old library for parsing XML it generates an error since it cannot identify
the language.`
That seems worrisome to me... considering then, that most html pages will
break the librdfa parser.
@lewismc should we not test more thoroughly *before* merging to master?
Maybe a separate branch instead?
Also, I would think that all of our current rdfa parsing tests should be
duplicated for the librdfa parser to ensure that it is *at least as stable as
our current rdfa parser*. TBH, I'd be in favor of adding this into version 2.4
rather than 2.3 so we have more time to thoroughly test the module.
