Trying to define a base type of PropertyType,
And derived several types from
this base type. Where the name element is restricted to
a fix list in each derived type.
Have a file that should have a list of
these derived types in a specific order.
In XML spy when I try to validate the
file it complains that the second Property entry does not have DisplayName, when it has a Type.
Why does it think all Property entires are DisplayPropertyType's
??
XML File
