Now that Declaration implements nsIStyleRule, we don't need the memory overhead of storing a StyleRule object for style attributes. We also need to change this prior to patch 5, because the changes in patch 5 that will allow rules to change (but declarations not) would otherwise break due to style attribute object merging done by nsAttrValue::ParseStyleAttribute. --HG-- extra : commitid : Ij4yRdba7wa
