one stated goal of polyglot documents though is allow the xml toolchain to be
used to generate documents served as text/html. Most SVG tools are going to
wrap the long svg path attributes as xml normalisation and/or svg white space
rules mean that it is safe for them to do so.

thus not allowing newlines here just to obtain an identical dom seems
optimising for a non-use case (the number of times when you are going to want
to serve the same thing with two different mime types and have identical white
space in attributes must be vanishingly small) while preventing one of the main
aims of the specification (allowing you to generate xhtml+svg+mathml documents
served as text/html in a safe way.

I think that I'd say don't put newlines in the title attribute, or attributes
holding URI, but allow them elsewhere, noting in the introduction that white
space differences in attributes are ignored except as noted in the body of the
