[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: Holographic XML
 Related to this there was an interesting presentation at XML Prague earlier this year "A Time Machine for XML", discussing a third 'time' axis for XML, which could be navigated in Xpath as later:: or first:: etc. There is as yet no implementation or underlying structure to support this, as far as I know. In our work we can represent multiple XML documents, e.g. versions through time, in a single 'delta' document and although this is very powerful in helping to solve a certain class of problems, it is much more complex that vanilla XML. And as one of the strengths of XML is its simplicity, it is best not to lose that.
