Hi Andrew, > Don't forget that XSD can stream xml to validate it, hence the 'look > down' restriction. Full XPath requires the whole document in memory. That's an excellent point. However, the XML Schema language should not force a schema designer to always look down just so that implementations can support streaming. If it is important for a schema designer to make use of streaming then he will design his XML Schema <assert> elements to always look down, but if streaming is not important to him then his <assert> elements should be able to look anywhere, including across documents. /Roger
