XTCE13 — Possible typo of word "difference" instead of "different"

"There are eight different verifiers each associated with difference states in command processing"

Correct the typo until a better verifier description comes along

Replace the documentation text for the complex type VerifierSetType to correct the spelling error. Note that the change is exactly 1 word.

The previous definition of this type:

<complexType name="VerifierSetType">
<annotation>
<documentation xml:lang="en">Describe a collection of unordered verifiers. A command verifier is a conditional check on the telemetry from a SpaceSystem that that provides positive indication on the processing state of a command. There are eight different verifiers each associated with difference states in command processing: TransferredToRange, TransferredFromRange, Received, Accepted, Queued, Execution, Complete, and Failed. There may be multiple ‘complete’ and 'execution' verifiers. If the MetaCommand is part of an inheritance relation (BaseMetaCommand), the 'complete' and 'execution' verifier sets are appended to any defined in the parent MetaCommand. All others will override a verifier defined in a BaseMetaCommand. Duplicate verifiers in the list of CompleteVerifiers and ExecutionVerifiers before and after appending to the verifiers in BaseMetaCommand should be avoided. See MetaCommandType and BaseMetaCommandType for additional information.</documentation>
