The point I was making is that 'scope' is introduced in a total of about 3-4 sentences in total in the XML + XLink specs. It's actually quite easy for an implementer to miss. I'm not complaining - I'm saying that it would be useful to discuss whether we can all implement this easily and if so how. [BTW how much freely available is actually out there which implements any/all of these attributes?] The touchstone of XML-applications - the desperate Perl Hacker - is not necessarily going to build a stack of the attributes of an/every element. And I'd represent - gently - that some people (at least one) are going to have met attribute re-mapping for the first time and possibly get muddled. For example it seems that a Node must have 2-3 sets of methods: getAttributeValue(String attName); getPseudoAttributeValue(String specialAttnameInContext) and getPseudoAttributeValueAfterRemapping(String possiblyRemappedAttributeName) If this is a useful way forward (other than the somewhat contrived names) it would be nice to know. If not, what? P.
