The logic of each element appended to a GrammarBuilder is applied by recognition engines in the order in which it was appended.

The semantics defined by the SemanticResultKey are appended GrammarBuilder with results that can be accessed on recognition as a SemanticValue instance obtained using the string key to index the Semantics property on the returned instance of RecognizedPhrase.

Care should be taken in appending to a GrammarBuilder object with a SemanticResultKey instance.

An exception will be generated during the use of a Grammar generated from a GrammarBuilder with an SemanticResultKey appended its grammar logic will result in more than one instance of SemanticResultKey with the same tag value and at the same level in the recognition semantic tree are created.
