vs:TAPType BOOLEAN?

Dear Reg/DAL,

VODataService defines the TAPType type which is an enumeration of 
possible values for the content of a <dataType xsi:type="vs:TAPType">
element, defining the data type of a table column (see the first
table in VODataService version 1.1 section 3.5.3).
One of the entries is in this list is "BOOLEAN". 

However, TAP version 1.0 section 2.5, which lists data type mappings 
for uploaded TAP tables, has no corresponding entry - the space
opposite the VOTable "boolean" type is labelled "Not supported".

Since there appears(?) to be no BOOLEAN type in ADQL, I suspect that
the inclusion of BOOLEAN in the VODataService TAPType list is in
error, but perhaps there's some other explanation.

Can any expert on VODataService (Ray?) or DAL (Pat?) comment?

thanks

Mark
