Language is not a property of the literal. Language is a specific context of interpretation. It is similar to datatyping. You don't say that the literal "5" *is* an xsd:integer, forever and always, wherever it occurs. Rather, in a given case, the literal may occur with a datatype context that gives it interpretation. A literal is not a pair ("string", "lang"). The M&S is wrong. There, I've said it ;-) >> And especially since literals are >>> now tidy, > > The pair above is just as tidy as "string". ??? So now, <key xml:lang="en">pan</key> <key xml:lang="sp">pan</key> do we get xxx key "pan" . ("en") xxx key "pan" . ("sp") or xxx key ("pan","en") . xxx key ("pan","sp") . ??? Now which represents tidy literals? And does that mean that for *every* query that compares literals one must specify language? And what about comparison of literals where one is specified for language and the other is not, do they match? No? Why? Nope. I don't think that any of our discussions over the past few months have considered literals to be anything but the string.
