Maybe we could finally break the cycle of namespace violence by re-examining the decision to drop the src pseudo-attribute, which appears to have happened between the 18-May-1998 draft of Namespaces in XML (http://www.w3.org/TR/1998/WD-xml-names-19980518) and the 16-September-1998 draft (http://www.w3.org/TR/1998/WD-xml-names-19980916). It seems that we have a problem involving overloading an identifier with behavior, and that separating the behavior from the identifier might plausibly let us get on with our real work rather than debating the nature of identifiers. Perhaps something like xmlnssrc:prefix="retrievable SRC URI"? Not all namespaces would have to have it, but not all namespaces are intended for retrieval anyway. It'd give us a much clearer line of demarcation as well. Then we could fight about what lived at the end of SRC, but we're doing that anyway.
