Hmm, from [1]: | Externally defined character entities other than the five | pre-defined ones (<, >, &, " and ') are | only supported if the document references a public identifier | for which there is a mapping in Mozilla’s pseudo-DTD catalog | and the document has not been declared standalone. | | In older versions of Mozilla as well as in old Mozilla-based | products, there is no pseudo-DTD catalog and the use of | externally defined character entities (other than the five | pre-defined ones) leads to an XML parsing error. There are | also other XHTML user agents that do not support externally | defined character entities (other than the five pre-defined | ones). Since non-validating XML processors are not required to | support externally defined character entities (other than the | five pre-defined ones), the use of externally defined | character entities (other than the five pre-defined ones) is | inherently unsafe in XML documents intended for the Web. The | best practice is to use straight UTF-8 instead of entities. | (Numeric character references are safe, too.) But that's just baffling. What's the point of including entities in the DTD if they're not supported? The XML standard says: | Note that non-validating processors are not obligated to read and | process entity declarations occurring in parameter entities or in | the external subset; for such documents, the rule that an entity | must be declared is a well-formedness constraint only if | standalone='yes'. standalone='no' is the default, so the standards-based argument does not seem very convincing. Do you have any more details about this firefox upgrade problem? Does the problem show up in other browsers? Thanks again.
