Well-Formed and Valid

Suppose that I have an XML document, but I don't claim that it's valid. This could mean any of the following:

  1. There's no DTD for this document, or
  2. There is a DTD for this document, but it's off on a server somewhere and I don't want to get it, or
  3. There's a DTD available right here, and in fact if I were to check, the document would be valid, but all I'm doing is displaying or indexing it, so I don't care about the DTD.
