[Dillo-dev] SGML question

Hi! Before I start digging to the specs, someone may answer me this question faster: Should stripping spaces from attributes done before or after the conversions of entities? E.g., if I have something like <td align="char" char=" "> is the value of the "char" attribute " " (one space) or "" (empty)? Dillo does the second, so it is not possible to align characters at spaces. BTW, does someone know a good and simple way to retrieve informations about other the user has specified via $LC_...? I need this for the standard value of the "char" attribute, which depends on the language of the document (or a content part). Sebastian
