P190 has symbolic content in version 7.1.1

This property associates an instance of E90 Symbolic Object with a complete, identifying representation of its content in the form of an instance of E62 String.

This property only applies to instances of E90 Symbolic Object that can be represented completely in this form. The representation may be more specific than the symbolic level defining the identity condition of the represented. This depends on the type of the symbolic object represented. For instance, if a name has type Modern Greek character sequence, it may be represented in a loss-free Latin transcription, meaning however the sequence of Greek letters.

As another example, if the represented object has type English words sequence, American English or British English spelling variants may be chosen to represent the English word colour without defining a different symbolic object. If a name has type European traditional name, no particular string may define its content.
