>
> Command code typically refers to context values using fixed keys. This makes
> it difficult to create commands that are truly re-usable; it's often
> necessary to include commands to move values between keys so that the values
> are where the various commands expect them.
> The attached code allows command code to refer to keys using a "logical" name
> which is mapped at runtime to the actual keys to be used to access the
> context. The mapping between the logical and actual names is specified per
> command instance and is easily set up in a catalog XML file.
> The package also supports nested hierarchical contexts and allows contexts
> within a hierarchy to be logically mapped in a similar way.
