According to http://www.w3schools.com/tags/tag_button.asp, the type
attribute of the <button> tag is optional. Is the UA at liberty to
choose any type it wishes if the attribute is omitted? Does the
presence or lack of a DTD impact the answer?

W3Schools is rather error prone, in this case they are simply missing some
information. Try the spec instead:

type = submit|button|reset [CI]
This attribute declares the type of the button. Possible values:

* submit: Creates a submit button. This is the default value.
* reset: Creates a reset button.
* button: Creates a push button.

[From the specification:]

It's worth pointing out two things, both related to IE:

1. IE incorrectly assumes 'button' for the default value.
2. IE gets the whole mechanics of the BUTTON element wrong
when used for form submission.
