By default, nxml-mode looks at the name of the root element and decides to validate the document against some schema based on that name.
I would like to disable this and just validate that the document is well-formed, since I edit documents in my own custom format with element names that coincides with some schema nxml-mode knows about but that is not relevant to my purposes.
I know I can toggle validation using C-c
C-v
, but I'd prefer to keep the check for well-formedness enabled at all times, if possible.
