Hi Folks,

Thank you (again) for your outstanding responses.

I found your responses surprising. In a nutshell, you told me that many, if not most, data formats – both text and binary – are extensible.

XML, it seems to me, has always made it a point to advertise that one of its virtues is that it is an extensible data format. After all, it’s built right into its name: Extensible Markup Language. But now you tell me that, in fact, extensibility is part of many data formats. XML is not unique in that regard.

Isn’t that disheartening?
