Yes. You forgot the doublequotes around the argument, which are
essential at least in this example. :-)

Yep. And

  <URL "http://a.b.c/cd/">
  <URL "http://a.b.c/cd/" >

should give

  <a href="http://a.b.c/cd">http://a.b.c/cd/</a>
  <a href="http://a.b.c/cd/">http://a.b.c/cd/</a>

Because of WML interprets the last slash in the first example as the
XML conform ending slash of a single tag in opposite to double tags,
where the ending slash is the first character in the closing tag.

That means, 

  <URL http://a.b.c/cd/> 

is treated like 

  <URL "http://a.b.c/cd" />

and not like 

  <URL "http://a.b.c/cd/" >

See http://www.engelschall.com/sw/wml/docs/docs/wml_macros.html in the
section "About Simple Tags".

HTH.
