1. As noted in the previous meeting, both the ComplexContent and ComplexElement productions include a "Prefix" element. Mike stated that this redundancy does exist in DFDL, but it sometimes necessary, e.g. for embedded groups. Steve suggested that, if this did need to be changed, we would do so with restrictions rather than a change to the productions.
2. Suman suggested that the present grammar specification does not satisfactorily cover the case where the start of an array needs to be aligned, with individual array elements automatically being aligned. Mike suggested that this can be dealt with, in a DFDL schema, by encapsulating the array in an element or sequence.This would require the author to build additional encapsulation around the array, which Suman felt would be unnatural, and suggested it would be more natural to introduce a property to explicitly deal with this situation. Mike observed that the XML specification treats arrays as simply adjacent elements, so we should minimize the number of properties which affect an entire array rather than each individual element. Mike and Suman will collaborate on a concrete proposal to address this.
3. Mike expressed discomfort with the use of "binary" and "opaque" to describe raw data, as these words ,ay be ambiguous. "opaque" in particular may refer to unparsed data, or to anyType elements. Suggested alternatives included "octets", "bits", "raw" and "blob".
4. The SequenceContent production currently contains a "finalUnused" element. Mike wondered whether this would best be moved to the Sequence production. Suman felt that there would then be issues with prefixes and suffixes. The meeting saw no good reason to change this.
5. Precedence order needs to be defined. Steve and Geoff will attempt to define a static order.
6. Regarding the query raised at the previous meeting concerning initial prefix Separators and final postfix Separators, Mike confirmed that these had been removed following comments in a previous draft of the document. They had originally been intended to support certain properties which could be now be defined using other features of the grammar.
