When you run Saxon on the .NET platform, there are two XML parsers available: the System.Xml parser
supplied with the .NET platform, and the JAXP parser that comes with the OpenJDK library, which is supplied
as part of the Saxon product.
Saxon generally uses the Microsoft System.Xml parser by preference. However, you can force Saxon
to use the OpenJDK parser by calling processor.SetProperty("http://saxon.sf.net/feature/preferJaxpParser", "true").
(It is not possible to do this from the command line.)
Note that the Microsoft parser does not notify ID or IDREF values from the DTD, or expand attributes with
fixed or default values, unless DTD validation is requested. This can be requested using the -v option on the
command line, or via the API. (See the DtdValidation property of the DocumentBuilder
class)
At present, unparsed entities are ignored when the Microsoft parser is used.
The XSLT functions unparsed-entity-system-id()
and unparsed-entity-public-id()will therefore not work.
