This Simple DataType defines a string value that shall be normalized according to Unicode Annex 15, Version 7.0.0, Normalization Form C.

NOTE: Some Unicode characters have multiple equivalent binary representations consisting of sets of combining and/or composite Unicode characters. Unicode defines a process called normalization that returns one binary representation when given any of the equivalent binary representations of a character. The Win32 and the .NET Framework currently support normalization forms C, D, KC, and KD, as defined in Annex 15 of Unicode. NormalizedString uses Normalization Form C for all content, because this form avoids potential interoperability problems caused by the use of canonically equivalent, yet different, character sequences in document formats.
