For example, the proposed "xml:stylesheet" PI allows you to attach a stylesheet to any XML document without having to tamper with the document's DTD (as by adding a STYLE element or attribute). I can't see designing a new document type and using PIs, though. As you say, elements or attributes do the work. -- John Cowan http://www.ccil.org/~cowan cowan@c... You tollerday donsk? N.
