Creates a link to the parent of a [WikiPage].  This is mainly intended to work with [WikiAttachments], that is, if the page you are referring to is an attachment, it will generate the correct link.

Why would you use this instead of a standard anchor?  The LinkToTag automatically adds things like the correct class information (for styles), the jspwiki.baseURL property, attachment links, etc.

!Usage

<wiki:LinkToParent page="<page name>" format="anchor|url">

;__format__: If "anchor", creates the full hyperlink (<a href="...">link text</a>); if "url", outputs only the URL.

The parent of this attachment is <wiki:LinkToParent><wiki:ParentPageName /></wiki:LinkToParent>.
