Canonical links are implemented by placing the "link-to" URL inside angle brackets and putting the link HTML element in the page to which it applies:

<link rel="canonical" href="http://www.link-to-page-here.com/" />

The answers are in http://greenbytes.de/tech/webdav/rfc5988.html#rfc.section.5: so "yes", "no", and "no".

(The link relation "canonical" has it's own spec -- https://www.rfc-editor.org/rfc/rfc6596 -- but of course uses the general header field syntax defined in RFC 5988)
