Martin, I'm glad that you have success in using this capability.
The attached files were very helpful for review. I'm surprised that more extensive review was not performed by the old Xalan team. The code example operates similar to using the XPath document function, but uses top-level parameters with nodeset values referencing preparsed XML documents. The ability to use preparsed XML document fragments multiple times within a transformation can have its performance benefits. The example only tested a single XObjectPtr instance. A follow-up capability that should be tested is whether the XObjectPtr parameter value is sufficiently free of side-effects so it can be used multiple times within a single XSLT stylesheet. I will try to provide example documentation so this capability can be integrated into the product for general use. I will also try to build some good tests for documentation purposes.
