Subject: Re: [DFDL-WG] elementFormDefault and the form attribute on
element declarations
Section 5.1 of the spec has 'Standard XSDL namespace management' in its
list of what a DFDL schema consists of. Section 5.1 does not go on
explicitly to exclude 'elementFormDefault' attribute or 'form' attribute,
so my reading is that both these are therefore allowed.
We could expand what is meant by 'Standard XSDL namespace management'. But
if we do that we should make sure that we do so in any other areas that
are a bit vague. For example, we disallow complex type derivation and
substitution groups so does this imply that 'final' and 'block' on complex
types and elements are prohibited regardless of setting? For example, we
disallow identity constraints but does that mean that 'id' can never be
used on schema objects?

Neither the term "elementFormDefault" nor the term "unqualified" appear in
the DFDL Spec. So we're silent about whether these are allowed or not in
DFDL schemas.
We should specify what of this XML Schema behavior is allowed, which I
believe means add a line to each of the lists in section 5.1 of things
used and not-used/reserved from XML Schema.
FYI: Today the Daffodil implementation implements elementFormDefault on
the xs:schema but not the form attribute on element declarations. We have
tests that exercise elementFormDefault in qualified and unqualified and
not specified at all (which defaults to "unqualified" behavior in XSD, so
we're consistent with that.)
