The abstract interface to XSLT extension packages.

An extension package is a collection of all extension elements and extension functions associated with the same namespace URI.

For each extension package supported by the particular XSLT implementation, the separate derived class must be provided.

the namespace URI associated with this extension package

CreateExtensionPackageContext

virtual XExtensionPackageContext 
    CreateExtensionPackageContext() = 0;

IsExtensionElementAvailable

virtual bool IsExtensionElementAvailable(
    const CString &strLocalName) = 0;

Parameters:

strLocalName - the local name of the element

Returns:

true if the extension element with the given name is supported by this extension package; false otherwise

CreateExtensionElement

virtual XExtensionElement CreateExtensionElement(

true if the extension function with the given local name is supported by this extension package; false otherwise

FindExtensionFunction

virtual XExtensionFunction FindExtensionFunction(
    const CString &strLocalName) = 0;

Looks up the extension function with the given local name in this extension package.

Parameters:

strLocalName - the local name of the function

Returns:

the extension function with the given local name, or NULL if the function with this local name is not supported by this extension package
