Additional changes to Schema.pod

[Clif H. <c-h...@ti...>]

Graham,

I found the schema dump command was not documented.

Attached is a diff file with my changes.
This diff was taken against a Schema.pod file that
had my earlier changes applied.

Format of the diff command;
 diff -c Schema.pod.with.clifs.changes Schema.pod >! 2nd.Schema.pod.diff

Regards,
