actually, HTML attribute quoting seems to have changed over the years. as i remember, during the accessibility reform of dotlrn, quotes around HTML attributes were required. Nowadays, HTML5 does not require quoting attributes, HTML4 seems to recommend quotes, only XHTML requires it.
anyhow, i've added quotes to the HTML attributes of the admin pages of acs-subsite were i found it missing, since for variable attribute values omitting quotes is always dangerous.
