[pmwiki-users] Custom markup over multiple lines

[DaveG]

I'm trying to define a custom markup that spans text over multiple 
lines. Here's what I have:
Markup('^Country:', 'directives', '/^Country 
(UK|US|JP|AU|NZ|CA):(.*?)>><</im', '<div class="country $1">$2</div>');

There are two problems I'd like help with.
1] How to get the regex to span multiple lines?
2] The >><< terminator doesn't work. I tried "\>\>\<\<" to no avail. 
What's the right way?

In addition, is this the pmwiki way/syntax to define a markup that spans 
multiple lines?
