Consider the following example schema. XmlXpy says both examples are
valid if you hit the validation button while in schema view. But in
text
view it says the first example is not valid. Even in test view it says
the second
example in valid. Xerces says both examples are not valid.
As a C++ programming my overloading instincts make me want the
funtionality
displayed in these examples. Help me understand why XmlSpy validates
one
way in schema view and another way in text view; and also help me
understand
why my examples should not be valid. Please.
