{@extLink foo {@index "Foo Description"}}

"{@index "Foo Description"}" is parsed as the description for the external link instead of "Foo Description".

<a href="foo.html">{@index "Foo Description"}</a>

The link is lost and the output generated is
<a href="foo.html"><a id="FooDescription" class="searchTagResult">Foo Description</a></a>
