Коллеги, поясните , пожалуйста, Ignorable в WPF? В статье на МС вроде все слова знакомые, но вот зачем это нужно - не уловливаю:
Elements or attributes where the prefix portion of the element name are identified as mc:Ignorable will not raise errors when processed by a XAML processor. If that attribute could not be resolved to an underlying type or programming construct, then that element is ignored. Note however that ignored elements might still generate additional parsing errors for additional element requirements that are side effects of that element not being processed. For instance, a particular element content model might require exactly one child element, but if the specified child element was in an mc:Ignorable prefix, and the specified child element could not be resolved to a type, then the XAML processor might raise an error.
