  16 // The following requirement is tested:
  17 // When referencing a field of an uninitialized record value or field or omitted field
  18 // (including omitting a field at a higher level of the embedding hierarchy) on the left
  19 // hand side of an assignment, the reference shall recursively be expanded up to and
  20 // including the depth of the referenced subfield as follows:
  21 // a) When expanding a value or value field of record type, the subfield referenced in
  22 // the dot notation shall be set to present and all unreferenced mandatory subfields shall
  23 // be left uninitialized; when the assignment is used in a scope where the optional
  24 // attribute is equal to "explicit omit", all unreferenced optional subfields shall be
  25 // left undefined. When the assignment is used in a scope where the optional attribute is
  26 // equal to "implicit omit", all unreferenced optional subfields shall be set to omit.
  27 // b) Expansion of record of/set of/array, union and set values and intermediate fields
  28 // shall follow the rules of item a) in clauses 6.2.3 and 6.2.5.1, and clause 6.2.2.1
  29 // correspondingly.
  30 // At the end of the expansion, the value at the right hand side of the assignment shall
  31 // be assigned to the referenced subfield.
