The --dtdvalid switch is meant to be used with a filename argument.
If you don't need that because you're relying on the DOCTYPE of the

$ xmllint | grep valid
  --valid : validate the document in addition to std well-formed check
  --dtdvalid URL : do a posteriori validation against a given DTD

What is the "standard DTD" and which files or URLs does xmllint fail to
load?

That won't work, they're usually blocked.
