I also thought about underscore but it doesn't look good.

Essentially we do need a concatenation, that's why we used + (among other things) so perhaps we should use the period.

Trying to use a microID in an XHTML 1.1 document. W3C Validator
doesn't like it because it says:

character "+" is not allowed in the value of attribute "class"

The code in question is basically along these lines:
<span class="microid-mailto 
+http:sha1:23e9670868f6d2b16fe1f6b3db80c" ...

Any thoughts? Something I'm missing? Didn't know who else to ask about
the topic. Is the current spec of microID incompatible with some later
XHTML versions when using the "class" method?

Well, further research reveals that the 'class' attribute has a datatype
of NMTOKENS, i.e., a space-separated list of NMTOKEN productions, which
are defined in XML 1.0 as follows:

   Letter | Digit  | '.' | '-' | '_' | ':' | CombiningChar | Extender

The last two don't help us (they are things like umlauts and such), so
that means we're limited to letters, digits, periods, hyphens,
underscores, and colons. We're already using hyphens and colons are
separators, so I think we need to change from + to period or underscore.
So in this example that would be:

1. microid-mailto.http:sha1:23e9670868f6d2b16fe1f6b3db80c

or

2. microid-mailto_http:sha1:23e9670868f6d2b16fe1f6b3db80c

I don't have a strong preference between the two. The period feels more
like concatenation to me, but that's perhaps purely visual.
