Which microformat? That's a URI and so a more semantic place for it is
in <a href="urn:..."> or maybe <link href="urn:">.
It's actually a URN, a subset of URI which does not imply availability
of the identified resource. Doesn't this make it inappropriate for an
href in the context of a web page? I completely see where you're
coming from, though. If it were a URL then that would be more
appropriate for an href surely? See here for more info on this
distinction:

Getting more specific, it's actually an LSID for a microformat that is
still in development. More on LSIDs here:
http://lsid.sourceforge.net/#whatislsid
Having said all this, LSIDs can be made to behave like URLs via a Firefox addin:
http://lsid.biopathways.org/lsid_browser/lsid_browser_1_0_0.html
So perhaps sticking the LSID in the href might be useful after all.
However, providing a *direct* link to the resource described by the
LSID isn't the intended aim of the microformat; the LSID is in there
as metadata that describe a resource, while the normal hyperlink, if
there is one, probably points to something else entirely.

No, you do not use selector syntax in HTML attributes. You use selector
syntax in selectors.
OK, so "urn:lsid:ubio.org:namebank:530114" would actually be a valid
class name then? The LSID would almost certainly never be used as a
CSS selector (should never rule the possibility out, though), so if
it's valid in its unescaped form then that's great news.
To select a class attribute containing colons, you would using the first
example above without the back slashes and then in your CSS, you would
write this:
.urn\:lsid\:ubio\.org\:namebank\:530114 { color: green }
For it to work in IE6 (not sure about IE7), you need to use "\3A "
(including the space) instead of "\:"
.urn\3A lsid\3A ubio\.org\3A namebank\3A 530114 { color: green; }
If you put in an href attribute where it belongs, you would use this
instead:
[href=urn\:lsid\:ubio\.org\:namebank\:530114] { color: green; }
(This won't work in IE at all, even if you use "\3A")
See this test case:

That's all really useful to know, many thanks!
