First of all, in relate to the specification, I missed that
XmlDataDocument don't have the declaration of CreateNavigator.
I would tend to agree with you. But 'public' and 'internal protected'
are importantly different when third parties (users) wanted to
call such methods from non-inherited classes.
'public' methods can be called, but 'internal protected' methods can't.
So I think 'public virtual' is better than 'internal protected.'
BTW, MS document says that XmlNode.CreateNavigator() is 'public':
(With VB.NET syntax, it is explicitly declared as 'NotOverridable')
And I couldn't find the ECMA specification's definition for XmlDocument
class. Please tell me where that API specification is...
I can't find why this method is not virtual. If MS developers
didn't have to override it, they might leave it 'public.'
But on the other hand, 'InsertAfter' is overridable, and then
'CreateNavigator' should be 'public virtual' too.
Or if they have rational reason they don't want to override it, then
it should be 'public.'
Anyway, some bugfixes are required.
