<p class="MsoNormal">In DDI 3.2 there is a specific differentiation between valid and invalid (missing values) so that they are declared separately. In PhysicalDataProduct the PhysicalStructure/DefaultMissingData can be used for this as this is a description
of a specific file type (like SAS, etc.). Larry Hoyle or Achim Wackerow can probably provide more details as they were looking at the new structure for Missing Values in this context while it was being developed.<o:p></o:p></p>

<p class="MsoNormal"> Do any of the DDI documentation/codebook generating packages handle extended Stata/SAS missing values? .a-.z ; "."? Our analysis datasets (as opposed to the original questionnaires) invariably use multiple sets of special missing codes,
and converting every thing into faux numeric missings (-1---9) for instance kind of defeats the purpose.<o:p></o:p></p>
