This is by design, though I'm not sure about the decision.

First, there's the issue of compatibility with other markdown parsers.
% Markdown.pl
hi

hi

isn't a valid HTML tag, but Markdown.pl has always been flexible about
allowing extensions. So, for example, you might use an tag for equations,
postprocessing the output of pandoc with a tool like gladtex to convert these into
images.

So I haven't required tags to be valid xhtml tags. This does occasionally lead to
undesired results, e.g. if you write something like ''. So maybe this should be reconsidered. (You can always write '' if you really need this.)

Well, I think it would make sense to follow W3C XML standard which does not allow
spaces in tag names (for a good reason):
<this_is_a_valid_tag attrib="value"></this_is_a_valid_tag>

If every occurence of < outside of valid tags / CDATA sections did get replaced by
character entity <, output would be valid XML which would be nice :-)

The problem is that the markdown spec says that embedded HTML is okay, and HTML
allows attributes without values, such as

. This isn't a space in a tag
name; it's a tag followed by a bare attribute.

Pandoc could enforce a stricter standard, but I want to maintain compatibility with
standard markdown where possible. Markdown.pl will take '' => '',
by the way.
