LSX-00162
string "~S" is an invalid default for the complex type
Cause
If the {content type} is a simple type definition, then the string must be valid with regard to the simple type definition as defined by String Valid (3.14.4). If the {content type} is mixed, then the {content type}'s particle must be emptiable as defined by Particle Emptiable (3.9.6). However, one of these conditions was not met, resulting in this error.
Action
Make the default string a valid default with regard to the complex type definition.
