I've noticed that WordPress seems a little loosey goosey when it comes to quoting styles in the HTML it generates. Sometimes WordPress uses single quotes, other times it uses double quotes
<link rel='next' title='An Example' href='http://example.com/foo/' /> <link rel="canonical" href="http://example.com/foo/" />
I know that single quote are, as of HTML5, technically "OK", but I'm weird and particular about how my HTML looks. Is there a way to tell WordPress to always use double quotes? If not, is there a plugin that might do this for me, or can someone point me to the appropriate do_action/apply_filter points so I can investigate this one my own?
