Regina Henschel commented on OFFICE-3995:
-----------------------------------------

In case of MathML we have element {{<math:math>}} in 14.6 part 3.
 LibreOffice writes
 {{xmlns:math="http://www.w3.org/1998/Math/MathML"}}
 as attribute of {{<office:document>}}
 and later use MathML without prefix e.g.
 {{<draw:object>}}
 {{ÂÂ <math xmlns="http://www.w3.org/1998/Math/MathML";>}}
{{ÂÂÂÂÂÂ ÂÂ}} _content_
 {{ÂÂ </math>}}
 {{<draw:object>}}

BTW: Is LibreOffice correct here? Or should that be
 {{<draw:object>}}
 {{ÂÂÂ <math:math xmlns="http://www.w3.org/1998/Math/MathML";>}}
{{ÂÂÂÂÂÂÂÂ Â}}_content_
 {{ÂÂÂ </math:math>}}
 {{<draw:object>}}

I want to get something similar for SVG, so that it can be written as e.g.
 {{<draw:image>}}
 {{ÂÂÂ <svg xmlns="http://www.w3.org/2000/svg";>}}
{{ÂÂÂÂÂÂÂÂÂÂ}} _content_
 {{ÂÂÂ </svg>}}
 {{</draw:image>}}
 I want, that it is possible to directly use documents created by Inkscape for example, without larger changes.

Michael, do you mean there should be something like the following?
 element {{<orgsvg:svg>}} by
 {{{{xmlns:orgsvg="http://www.w3.org/2000/svg"}}}} in {{<office:document>}}
 and later use as e.g.
 {{<draw:image>}}
 {{ÂÂÂÂ <orgsvg:svg xmlns="http://www.w3.org/2000/svg";>}}
{{Â Â Â Â Â}}_content_
 {{ÂÂÂÂ </orgsvg:svg>}}
 {{</draw:image>}}

> Currently applications need to use the <office:binary-data> element to store an embedded SVG-image, in case they will save to a single XML file (flat ODF). That means that the SVG-image has to be encoded to BASE64. But an SVG-image is an XML-document and therefore it would be possible to use it directly, similar as done with MathML objects. The proposal has the changes that allow use of native SVG for images where now <office:binary-data> is needed.
> Remarks to the proposal:
> The namespace attribute in element <svg:svg> is needed, because OpenDocument producer bind the prefix "svg" to the namespace "urn:oasis:names:tc:opendocument:xmlns:svg-compatible:1.0".
> The referenced document is a Candidate Recommendation. In case it will be released until the release of ODF 1.4, the URL has to be adapted.
> I'm not sure, whether the restriction "at most one" is correctly described by the schema.
> My proposal is not, to use <svg:svg> instead of the <draw:image>, because then the useful attributes draw:mime-type and draw:filter-name, and using <text:p> element for e.g. a caption would not be possible. And the proposal is not about adding an <svg:svg> element as drawing object on same level as e.g. <draw:rect>.
> Defining svg-svg follows the way it is done for math-math.
> I'm not sure, whether to force xlink in case of package format. That needs discussion.
