The semicolons are not needed, those are added by the transforming
program. The semicolon is just a sperator in vCard. In HTML the
individual tags act as the seperators.

This is actually incorrect, an additional <... class='adr'></...> is
needed wrapped around all the postal information.

No, the second one is not correct.

That is very acceptable, in the case of URL, since the 'a' is the most
semantic, the information is retrived from the href, but in the case
of fn and n the string Jack ... is used.

There is no exact rule on what follows what. In X2V for certain
properties certain attributes are looked at first. For dtstart, dtend,
dtstamp and other date-time elements the title='' element is looked at
first, for URL and eMail, the href='', for images the src='', for
others the node value is used or something like alt, or longdesc, etc.
There is not an exact science to it yet.
