Processing Instruction
It would be nice if an XML Processing Instruction was added as a way of associating a micro-summary with an XML resource. Furthermore, a content type for the format should be established.
<?micro-summary type="application/micro-summary+xml" href="/summary.xml"?>
The best part of using a processing instruction is that it works in all XML languages without breaking anything if the client application doesn't support the feature. Daniel Schierbeck 05:23, 20 Mar 2006 (PST)
