=head1 NAME
WML:href - Enhanced Hyperlink
=head1 SYNOPSIS
<use name="WML:href" />
<href url="..." [name="..."] [image="..."] [hint="..."] [target="..."] />
=head1 DESCRIPTION
This is an interface to the standard HTML anchor tag (C<E<lt>a
href="..."E<gt>...E<lt>/aE<gt>>). The intended use of C<E<lt>hrefE<gt>> is to
simplify the creation of hyperlinks. The following
<href url="THE://URL" />
<href url="THE://URL" name="THE_NAME" />
<href url="THE://URL" image="THE_IMG.EXT" />
<href url="THE://URL" name="THE_NAME" image="THE_IMG.EXT" />
<href url="THE://URL" hint="THE_HINT" />
<href url="THE://URL" name="THE_NAME" image="THE_IMG.EXT" hint="THE_HINT" />
gets expanded to
<a href="THE://URL"><tt>THE://URL<tt></a>
<a href="THE://URL">THE_NAME</a>
<a href="THE://URL"><img src="THE_IMG.EXT" alt="" border=0></a>
<a href="THE://URL"><img src="THE_IMG.EXT" alt="THE_NAME" border=0></a>
<a href="THE://URL" onMouseOver="self.status='THE_HINT';return true"><tt>THE://URL<tt></a>
<a href="THE://URL" onMouseOver="self.status='THE_HINT';return true"><img src="THE_IMG.EXT" alt="THE_NAME" border=0></a>
