D.1 Title, Description and Caption of Graphical Elements

...

When transforming from another document format to OpenDocument the short names, like HTML's alt text on the {{<img>}} elements should be mapped to the <svg:title> element.

User agents should not manufacture names for the <svg:title> element, such as using the drawing object name followed by a cardinal number in a string as it is used for accessibility. Such name assignments provide no semantic meaning to the user.

...

D.1.1 Guidance for authors

Authors should not assign names to objects having no semantic value. If no name is assigned the caption text will be used in its place. The <svg:title> element should take precedence over the caption text for accessible name assignment by the user agent.

Assignment of the long description should only be necessary when a drawing object is significantly complex and the user needs more information to describe it. Long descriptions would be more applicable to drawing groupings than basic drawing shapes.

D.2 Hyperlink Titles

When transforming from another document format to OpenDocument the alt text of hyperlinks, should be mapped to the office:title attribute of <text:a> 6.1.8 elements or <draw:a> 10.4.12 elements. When exporting OpenDocument documents to HTML, the contents of title text should be mapped to title attribute text on HTML anchor tags. As a minimum, authoring tools should provide a mechanism to provide the hint text.
