source - A source String to the Action
param - The Parameters for this invocation
Returns:
Map The returned Map object with sitemap substitution values which can be used in subsequent elements attributes like src= using a xpath like expression: src="mydir/{myval}/foo" If the return value is null the processing inside the element of the sitemap will be skipped.
Throws:

protected String getUpdateQuery(Configuration conf)
                         throws ConfigurationException
