Subject: Re: [office] proposal for ODF 1.2: extension of vertical relationvalues for certain anchor types
Dear TC members, finally after the solution of my problems to post to the mailing list I can post the information I have already given in yesterday's TC call.

The current restriction that certain vertical relations are only allowed for certain anchor types is expressed in prose not in any XML or related formal language. Applications, which only support ODF 1.0 or ODF 1.1, can in general not handle the new proposed combinations of vertical relation and anchor type. I assume that these applications will fall back to an application dependent default combination of vertical relation and anchor type. From my point of view the expected impact on the rendered document in an only ODF 1.0/1.1 supporting application is, that the object is not at the same position as in an ODF 1.2 supporting application. I do not expect any data loss.
