References to W3C DTDs

During 2010-11, W3C took steps to reduce the burden of meeting requests for commonly-referenced documents such as the DTD for XHTML. The W3C web server routinely adds an artificial 30-second time delay for such requests. In response to this, Saxon now includes copies of these documents within the issued JAR file, and recognizes requests for these documents, satisfying the request using the local copy.

This is done only in cases where Saxon itself instantiates the XML parser. In cases where the user application instantiates an XML parser, the same effect can be achieved by setting the StandardEntityResolver as a property of the XMLReader (parser).

The documents recognized by the StandardEntityResolver are:

This Saxon feature can be disabled by setting the configuration property ENTITY_RESOLVER_CLASS to null; it is also possible to set it to a different EntityResolver class (perhaps a subclass of Saxon's StandardEntityResolver) that varies the behavior. If an EntityResolver is set in the relevant ParseOptions or in an AugmentedSource then this will override any EntityResolver set at the configuration level.
