Hi Richard
In 8.3.0.0 we released the integration with Wiris MathType that allowed authors to use the MathType tool for authoring.
In 8.3.1.0 (April/May timeframe) we are intending to provide the first step in the publishing of the authored MathML. For HTML we will provide a method to pass the MathML through to the HTML for the browser to render (most browsers render MathML natively). For PDF we will pass the MathML through to the content processed by the APP DLL and use APP's MathJax library to render the MathML.
In 8.3.2.0 (approx November timeframe) we are planning to go a step further and provide an option to use a method of replacing the MathML in the content with images rendered by MathType. This will apply to both HTML and PDF outputs.
Arbortext does not ship MathType, it will be up to the customer to acquire that application.
I hope this clarifies the situation for you
Simon
