I'd like to show only links corresponding to the credentials of the
current user.
To make that as flexible as possible, I have thought of describing the
roles needed by the different pages in a XML document and the format
could be something such as:
<page id="admin" role="administrator" path="/administration"/>
The basic idea is that instead of directly using xhtml:a links, Models
and/or views would include elements such as : <l:a
ref="admin">administration</l:a> and this would be replaced by the
corresponding link depending on the credentials in the epilogue.
Now, wouldn't it be nice if this information was in my page-flow.xml?
That would actually be easy to do if the schema of the PFC vocabulary
was opened and allowed foreign attributes (and eventually foreign
elements in complex content elements).
I could then write in page-flow.xml:
<page id="admin" path-info="/administration/" view="admin-view.xsl"
foo:role="administrator"/>
and centralise the descriptions of the pages in a single document.
There are probably many other uses of such a flexibility and I think
that this is something that could probably be generalised...
Of course, I could already achieve something similar using PIs:
<page id="admin" path-info="/administration/" view="admin-view.xsl">
<?foo role="administrator"?>
</page>
Buts that's a poor man's hack that do not really use PIs for what
they've been created for...
