--- Comment #75 from Regina Henschel <rb.henschel at t-online.de> ---
Ink-graphics are originally specified in https://www.w3.org/TR/InkML/.
Microsoft uses it as extension to OOXML, details in "[MS-ODRAWXML]: Office
Drawing Extensions to Office Open XML Structure".

In ODF it could be stored as <draw:image> element in a <draw:frame> element.
Being an "image" does not mean, that it cannot be edited. Being able to create
and to edit such format, would be an implementation detail of LibreOffice, not
of the file format. [Similar as for SVG. Being able to edit an SVG would be a
feature of LibreOffice, not of the file format.]

The frame is able to contain different format versions of the same object and
it is up to the application to choose the format which it can handle best. So
it would be possible to store a original "ink"-format of MS Office in a
<draw:image> element for a later export to MS Office and have a second
<draw:image> with png for the current display.

Bug 140434 has a request for inking capability too. But I do not set it to
duplicate, because that report contains more feature requests.
