Subject: Re: [office-accessibility] alt text discussion
I am sorry for the confusion. I meant to say that we should provide a guideline document for user agent (or ODF-to-HTML converter) developers. I wanted to say that if some of the shapes do not provide alt text attributes(draw:name), because they are meaningless, it is fine for screen reader users. However, in this case, an ODF-to-HTML conversion program(or user agent that provides such function) need to supplement alt text attribute automatically for an image in HTML. An image, here is a shape in ODF without draw:name attribute. Otherwise, Web accessibility checker outputs multiple errors that there are no alt text for images, when it checks accessibility of HTML which is generated by ODF.

So you are saying that draw:name should be a schema required attribute or are you saying that the author should supply a draw:name and that the schema make it optional?

We want to propose that an HTML conversion method should be described for shapes(rectangles, etc) without "draw:name", if "draw:name should be optional". Screen reader users will not need to have meaningless alt texts, however, alt texts are required to be compliant with Section 508 and WCAG. It seems that MS Office provides ways to insert alt texts for any shapes, since a generated HTML documents from office documents should be compliant with 508. So we should describe that alt text should be inserted for a shape without "draw:name", "svg:desc", and a caption, as Null text when an ODF is converted to HTML format. In this way, an ODF editor can generate accessible HTML document. If you agree, then we need to find where we should describe such guideline.
