Conformance with other specifications

Saxon is dependant on the user-selected XML parser to ensure conformance with the XML 1.0 or 1.1 Recommendation and the XML Namespaces Recommendation. The syntax for names appearing in XPath expressions follows the XML 1.0 rules.

Saxon implements the <?xml-stylesheet?> processing instruction as described in the W3C Recommendation Associating StyleSheets with XML Documents. The href pseudo-attribute must be a URI identifying an XML document containing a stylesheet, or a URI with a fragment identifier identifying an embedded stylesheet. The fragment must be the value of an ID attribute declared as such in the DTD.

Saxon works with any SAX2-conformant XML parser that is configured to enable namespace processing. There is one limitation: on the startElement() call from the XMLReader to the ContentHandler, the QName (that is, the third argument) must be present. According to the SAX2 specification, namespace-aware parsers are not obliged to supply this argument. However, all commonly-used parsers appear to do so.

Saxon should work with any DOM-conformant XML parser, however, Saxon's DOM interface is tested only with Crimson and Xerces, and DOM implementations are known to vary widely.

When a DOM or JDOM tree is supplied as the transformation input, Saxon does not combine adjacent text nodes into a single node. Adjacent text nodes can occur as the result of user modifications to the tree, or as a result of the presence of CDATA sections or entity references, depending on the options in force when the tree was constructed.

When a DOM or JDOM tree is supplied as the transformation input, Saxon does not take the xml:space attribute into consideration when deciding whether or not to strip whitespace text nodes.
