I only want to show that in the file context.xml in Object 1, the namespace is \
<math:math xmlns:math="http://www.w3.org/1998/Math/MathML">, therefore, the prefix \
for every mathml element is mandatory. If the namespace were declared in the default \
namespace <math xmlns="http://www.w3.org/1998/Math/MathML">, then all the prefixes \
should be removed, but probably it can cause conflicts with other default namespaces.

It should be this:

is the first one of the EPUB3 features that we want to add to Calligra 2.7.
This version only supports math formulas saved as an embedded document, like \
LibreOffice and the OpenOffice variants save it. Calligra saves math formulas as \
inline mathML in the frame, which is not supported by this version. I thought that I \
could get some initial feedback while implementing support for the Calligra way \
