Andreas Guelzow  commented on OFFICE-3465:
------------------------------------------

If the xlink:href points to a file in the package the manifest should give us the type of image. If it is to an external file then we can't really store the type in the file since the external file might change.

> See similar issue OFFICE-3463
> In 10.4.4, the image (however obtained) is apparently parked in the <office:binary-data> and the only allowed attribute on <draw:image> is the <draw:filter-name>.  (There can be no xlink:href and the defaults for the other xlink attributes are apparently not relevant.)
> All that 10.4.5 <office:binary-data> provides base64binary of the image, but we are given no clue what the represented image format is. 
> Although there is a "should" about [SVG] and [PNG] but no indication how to tell what the <office:binary-data> represents (and if this case is relevant to [SVG], but if not, how is the SVG included in the element, or is that not provided for?)
> It is unclear how there is a choice to represent the image any other way than in binary data, unless the alternative is always with xlink:href and it is not permitted to cache the retrieved image in the <draw:image> element (because it would then not be refreshable).
> This is seriously underspecified as well as not being interoperably implementable from the information provided.
> Although ODF 1.1:9.3.2 is not much more specific.  There, the XLink information is described as not necessary when the <office:binary-data> is present, but it is not described as forbidden.
