// a string with expressions in the form ${key} to be replaced or
// ${key:format} which specifies a format function. NOTE syntax has
// changed from %{key}
// map: where to look for substitutions
// transform:
// a function to process all parameters before substitution takes
// place, e.g. dojo.string.encodeXML
// thisObject:
// where to look for optional format function; default to the global
// namespace
