jQuery will read it as id "test2" with the class "3"
While periods are allowed in the attribute I would advise against them,
as it's not just jQuery that could struggle with them but most CSS as
well, as #test2.3 with again read as id "test2" with the class "3".

Hi everyone,
the attached example-code shows a problem I encountered today (firebug
needed).
If an id-attribute contains dots, like
<p id="test2.3"></p>
jQuery isn't able to find it.
If the dots are replaced by underscores everything works fine.
Afaik there is no limitation for the id which prohibit dots as a used
symbol, so I guess this is a bug or for some reason not wanted?
Cheers
