And just to be explicit on something that bit me yesterday, for
DocBook 4.x the DTD is normative, whereas for 5.x the RNG is
normative. This means, practically, that you can have 4.4 documents
"valid" (against the DTD) that won't validate against the
non-normative 4.4 XSD (probably because of NCName constraints on @ids,
[no ":"], but there may be other stuff...).
Are there similar differences to be expected between RNG and XSD (my
guess is no)?
HTH,
