RE: [xsl] Saxon .Net API performance

Thanks Michael, that's really helpful. However, I don't understand how Tinytree 
is used by the Saxon API in .Net.

I'm using a .Net XmlTextWriter to serialize my objects to XML which are then 
built into an XdmNode (see code excerpt below), which is used as the input for 
transformation. As I understand, using the XmlTextWriter avoids using DOM. Does 
this use Saxon's tree model efficiently?

public XdmNode ReadObject(object objectToSerialize, Uri baseUri) {
            XdmNode result;

            using (MemoryStream stream = new MemoryStream())
         {
        XmlSerializer xmlSerializer = new 
XmlSerializer(objectToSerialize.GetType());
                using (XmlTextWriter xmlWriter = new XmlTextWriter(stream, 
Encoding.UTF8))
                {
                    xmlSerializer.Serialize(xmlWriter, objectToSerialize);

                    DocumentBuilder builder = 
XsltHelper.Processor.NewDocumentBuilder();
                    builder.BaseUri = baseUri;

                    stream.Seek(0, SeekOrigin.Begin);
                    result = builder.Build(stream);
                }
           }
            return result;
}

That's a very broad question!

I think probably the most important advice is to use Saxon's native tree model 
rather than running over the Microsoft DOM (which is possible, but slow). Most 
of the other things one can say are pretty generic, applying equally to any 
XSLT processor.
