From: Leigh Dodds <ldodds@i...> Date: Thu, 18 Oct 2001 16:16:08 +0100 There might be something in here about schema evolution as well. However I'm not familiar enough with native XML products to say how they'd handle this. E.g. if your schema is in a constant state of change (and they probably all are over time) or has yet to be finalized/standardised then locking it into a database structure might be unwise. Or am I off track on that one? Well, I can tell you how it works in eXcelon's XIS; unfortunately I'm not familiar enough with any of the others to say. In XIS, an XML document stored in the database need not be "locked" into the constraints of a schema. You can store XML documents that don't even have any schema (nor DTD, et. al.). You can then add new elements and attributes at will (and it's cheap to do so, and existing indexes are not affected, XPath expressions work, etc.). Validation is optional.
