---+++ Comments from Mark Taylor

Basically OK. I have a couple of suggestions for change/improvement:
   * *Schema versioning:*
      * Can this standard make use of the [[http://www.ivoa.net/documents/Notes/XMLVers/][XML Schema Versioning]] Note?  In particular, I'd like to see a =version="1.1"= attribute on =tableset= elements returned from tables-1.1 services.
   * *detail parameter:*
      * I would like to see, alongside =detail=min= , a =detail=max= option. Sometimes the client knows whether it wants/needs the whole tableset at once - it may be that a columnless tableset is no use to it, in which case the current proposal may end up returning a (possibly large) document which it doesn't want. However services (like !VizieR) can't be forced to return the whole tableset if it's huge.  So I'd suggest:
         * _[no detail specification]_ : service decides whether to include column detail or not _(unchanged)_
         * =?detail=min= : service must not include column detail _(unchanged)_
         * =?detail=max= : service may _either_ include all column detail, _or_ fail with a 403 Forbidden
      * I would make use in topcat of a =detail=max= option along these lines if it existed.
      * I still (cf my and Markus's email comments 16 Feb) don't see much value in the 303 redirect.

And some minor comments on the text:
   * Sec 3: a rogue backslash is visible in the output of the verbatim'd example element specification =http://some.name.space\#elementName=
   * Sec 3.1: in the PDF version, the URL =http://www.ivoa.net/xml/VOResource/v1.0= extends off the side of the page (a couple of words elsewhere in the document hang a long way off the right as well).
   * Sec 4: The table mentions both =ivo://ivoa.net/std/VOSI#tables= and =ivo://ivoa.net/std/VOSI#tables-1.1= standardID values, but the text about the tables endpoint just says "... the value of the standardID attribute must be =ivo://ivoa.net/std/VOSI#tables= ".
   * Sec 4: "(see example given in section 2.1)" - there is no section 2.1.
   * Sec 5: Example 1 contains =xsi:type="vs:ParamHTTP"= attributes, where the =vs= namespace is set as =xmlns:vs="http://www.ivoa.net/xml/VODataService/v1.0"= .  But the last sentence in section 4 says "this document recommends using the =http://www.ivoa.net/xml/VODataService/v1.1#ParamHTTP= interface type".  Is that an inconsistency?  Examples 2, 3 and 4 do use the v1.1 namespace (with =vod:= prefix).

---++ Implementation and Validators

Please note your implementation or validator in this section.

   TOPCAT: A pre-release version of TOPCAT that uses a VOSI-1.1-style tables endpoint (PR-20160413) is available at [[ftp://andromeda.star.bris.ac.uk/pub/star/topcat/pre/topcat-full_vosi11.jar]].  To use it, open the TAP window, point it at a VOSI-1.1 capable service (e.g. !http://www.cadc.hia.nrc.gc.ca/tap) and select from the TAP|Metadata Acquisition menu either "VOSI11-1step" or "VOSI11-2step".  It seems to work. -- IVOA.MarkTaylor - 2016-04-19
