From a0ddbb0ccba20123fc4e8243d962f86232282612 Mon Sep 17 00:00:00 2001

Subject: Changed FilesystemContext constructor to accept xalan::Locator* * all
 instantiations of a FilesystemContext are currently based on information
 provided by a xalan::Locator instance provided to the external function
 execute member method * this change hides the stylesheet path extraction from
 the actual function implementation
