Convert the passed schema to a pre-processed schema independent if it is
already minimal or not.

@param aSchema
The schema to be made minimal. May not be <code>null</code>
@return A minimal copy of the schema. May be <code>null</code> if the
original schema is not yet minimal and {@link #isKeepEmptySchema()}
is set to <code>false</code>.
@throws SchematronPreprocessException
In case a preprocessing error occurs
Convert the passed schema to a pre - processed schema independent if it is already minimal or not .
