Getting schema data types from XPathDocument/XPathNavigator

[Phil]

Is there an easy way to get the schema's data type for a XPathNavigator value?

I need to be able to determine the data type for the xml value based off of
an unknown schema and unknown xml file that is handed off to my code. I've
been able to figure out how to get the data type by reading through a
validating reader, but I can't seem to find an easy way to get this when
using XPath expressions.

The process I have is as follows:
1. Create a validating reader for the unknown xml file given to me.
2. Create a schema from the unknown schema file given to me.
3. Add the schema to the validating reader.
4. Create an XPathDocument using the validating reader.
5. Create an XPathNavigator from the XPathDocument.
5. Create XPathExpressions based off of the xpath information given to me.
6. Perform selects() on the expressions to get to the XPathNavigator with
the values I'm looking for. This is where I need to match the value to the
schema data type but I have had no luck figuring out a way to do it.

I don't think so. XPath 1.0 is schema-unaware language (because it was
published 2 years before XML Schema) and so is XPathNavigator API.
