0. ST
Definition

The character string data type stands for text data, primarily intended for machine processing (e.g., sorting, querying, indexing, etc.) Used for names, symbols, and formal expressions.

Invariantstext-null: xmlText and nullFlavor are mutually exclusive (one must be present) ((xmlText | nullFlavor).count() = 1)
2. ST.representation
Definition

Specifies the representation of the binary data that is the content of the binary data value
