Section 14.4 of the spec says: "An ordered sequence of n element children with either n or n-1 of those children with dfdl:floating='yes' is equivalent to an unordered sequence with the same n element children with dfdl:floating='no'." Does this mean that the extra restrictions we recently added for unordered sequences must also apply to floating elements? If so these would manifest themselves as: It is a schema definition error if an element with dfdl:floating 'yes' is an optional element or an array element and its dfdl:occursCountKind property is not ‘parsed’. It is a schema definition error if two or more elements with dfdl:floating 'yes' in the same group have the same name and the same namespace.
