!2 The GT Sub Page widget.
!note We are in the process of deprecating the ^ widget and replacing it with >.  This test proves that the > widget works.

Sometimes we want to conveniently create a link to a sub page.  We could do this by using the syntax ''!-SuperPage.SubPage-!'', but this is inconvenient.  Instead we want to be able to say ''!->SubPage-!''.

|SuperPage|true||

The widget should translate into a ? link of the form:
 * ''!->SubPage-!<a title="create page" href="!-SuperPage.SubPage-!?edit&amp;nonExistent=true">[?]</a>''
!|Response Examiner.|

|contents|&gt;SubPage<a title="create page" href="SuperPage.SubPage\?edit&nonExistent=true">\[\?\]</a>|true||

If the sub page is already present, then the widget should translate into a normal link.
