You're welcome. :-)

Thank you for investigating this.  It sounds like the "image
attribute" is an attribute specific to the "<svg:desc>" node, which is
specific to the odt format (content.xml), and not to SVG or PNG
metadata.  Because of this, I think the following phrase should be
changed like this:

- and the LaTeX code is embedded into the image attribute for further
- editing.
+ and the LaTeX [code|expression|equation|source, your choice. I like
+ "source"] is stored alongside the image in the ODT format. You can
+ later use TexMaths to edit the LaTeX [source] and regenerate the
+ image. If ever you find yourself without LibreOffice, you can unzip
+ the ODT and extract the source from content.xml to transfer the
+ LaTeX to another TeX editor.

This is possibly a bit verbose, but I think it's important to say how
work done with TexMaths can be transferred to another editor.  eg:
someone begins work with TexMaths and he/she needs to get some work
done on a system where LibreOffice cannot be installed.  And besides,
isn't that sort of thing part of the beauty/utility of TeX? ;-)

Kind regards,
Nicholas
