You probably need to register the extension functions.  The
following code is based on EXSLT.NET (a defunct gotdot.net
project), not Saxon, but the solution is probably similar:

Dim urlResolver As New XmlUrlResolver
Dim xmlDocument As New XmlDocument
Dim xslDocument As New XslTransform
Dim params      As New XsltArgumentList

xmlDocument.Load("file.xml")
xslDocument.Load(xmlDocument, urlResolver,
[Assembly].GetExecutingAssembly.Evidence)

params.AddExtensionObject(ExsltNamespaces.Common, New ExsltCommon)
params.AddExtensionObject(ExsltNamespaces.DatesAndTimes, New
ExsltDatesAndTimes)
params.AddExtensionObject(ExsltNamespaces.Math, New ExsltMath)
params.AddExtensionObject(ExsltNamespaces.Random, New ExsltRandom)
params.AddExtensionObject(ExsltNamespaces.RegularExpressions, New
ExsltRegularExpressions)
params.AddExtensionObject(ExsltNamespaces.Sets, New ExsltSets)
params.AddExtensionObject(ExsltNamespaces.Strings, New ExsltStrings)
params.AddExtensionObject(ExsltNamespaces.GDNDatesAndTimes, New
GDNDatesAndTimes)
params.AddExtensionObject(ExsltNamespaces.GDNDynamic, New GDNDynamic)
params.AddExtensionObject(ExsltNamespaces.GDNMath, New GDNMath)
params.AddExtensionObject(ExsltNamespaces.GDNRegularExpressions, New
GDNRegularExpressions)
params.AddExtensionObject(ExsltNamespaces.GDNSets, New GDNSets)
params.AddExtensionObject(ExsltNamespaces.GDNStrings, New GDNStrings)

xslDocument.Transform(xmlDocument, params, urlResolver)
