Having quotation punctuation generated by the user agent is utterly wrong. This
discussion has been going from a long time ago in the mailing lists. Quotation
marks for the /q/ element should be provided in the source so that 1)
non-graphical user agents can represent them, otherwise the content would be
flawed, and 2) to avoid issues that arise when writing content in different
languages: in French for example, the reference of the quote is written inside
the quote inside quotation marks (..., he whispered, ...) while in English
that's put outside the quotation marks; there's also problems with punctuation
in/outside quotation marks that's different in languages.
After all these arguments, the best is to prevent automatic generation of
quotation marks and notify web authors to add them outside the /q/ element
itself, since if quotes generation is preserved, then why not auto generate
periods for end of /p/ elements too?
