IMHO <nowiki> means that its content loses its "magicness": it must 
appear literal (for the user, not in the page source).

So the following would produce links:

As you're stripping "magic powers" to words which are not part of a spell.
Note that nowiking the namespace can be controversial, as it's not clear 
if the power resides in the namespace or not. I think the magic is in 
the square brackets and it should still be rendered as usual. The other 
option would be to make it a normal link but it's better not to add such 
esoteric constructs without a need (but could be added if proved easier 
to be coded!).

However,
 > [[image:foo.jpg|<nowiki>right</nowiki>|thumb]]
has the text right as right loses its ability to align it.

> [<nowiki>http</nowiki>://foo.com]
This doesn't match the URL format so would render literally. If they 
were double square brackets, it'd make an internal link, as opposed to 
normal [<a href="http://foo.com">[1]</a>] without <nowiki>

> <nowiki><b></nowiki>bold</b>
We want a literal <b>, so output is &lt;b&gt;bold + an unmatching bold 
closing tag to ignore/produce a warning.

> <b <nowiki>style="bloot;"</nowiki>

You call tag <b> with parameter 'style="bloot;"'. As tags don't get 
parameters separated by spaces, it's ignored(warning).
