Exporting a EPub 2 file to EPub 3 is great but Sigl seems to strip out Math ML when when opening an EPub 3 file. Is there a way to open an EPub 3 file that does not destroy the EPub 3 elements that are already in place? For example, the following Math ML tags are removed if it is included in an xhtml page in an EPub.
Code:
<li><p>Consider a population (or society) of <math display="inline" xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mi>N</mi><annotation encoding="application/x-tex">N</annotation></semantics></math> agents, each of which has wealth <math display="inline" xmlns="http://www.w3.org/1998/Math/MathML"><semantics><msub><mi>w</mi><mi>i</mi></msub><annotation encoding="application/x-tex">w_i</annotation></semantics></math>, where <math display="inline" xmlns="http://www.w3.org/1998/Math/MathML"><semantics><msub><mi>w</mi><mi>i</mi></msub><annotation encoding="application/x-tex">w_i</annotation></semantics></math> is the wealth of agent <math display="inline" xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mi>i</mi><annotation encoding="application/x-tex">i</annotation></semantics></math>. The number of agents, <math display="inline" xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mi>N</mi><annotation encoding="application/x-tex">N</annotation></semantics></math>, can be as little as ten to understand most of the model’s behavior.</p></li>
