The following page has been changed by assertions: http://wiki.apache.org/xerces/XML_Schema_1%2e1_Assertions ------------------------------------------------------------------------------ 1. [http://saxon.sourceforge.net/ Saxon basic] 1. [http://psychopath.sourceforge.net/ PsychoPath] + We have tried our best, to write an efficient implementation of XPath 2.0 integration for assertions. For nested elements having assertions, the child/descendant elements share the XPath (XDM) tree with the top most element. For each distinct XDM tree involved in assertions processing, we keep a reference of it's root node, and discard these references when assertions evaluation is complete for that tree. + + A caution for Schema authors: If we are specifying assertions for the root element of the XML document, a tree will be built for assertions processing, which could be as large as the XML document. To minimize this memory overhead, for large XML documents, assertions should be specified at an inner level of the XML documents, as far as possible. + '''References:''' --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
