<cache> element, which was added to facilitate the parsing of remote nodes. So, until I decide to bite the bullet it's a beta. The changes are as follows :* Added optional 'cache' element to xref element * Added optional 'content-type' attribute to xref element * Added optional 'xi:encoding' attribute to xref element * Added required 'created' attribute to node element * Added required 'modified' attribute to node element * Removed timestamp element from rev elementNote that the Perl widget is an alpha, warts and all, release. Feedback is welcomed and encouraged. I'll try and merge the old site with the new in the next few days.
