MathML is intended to facilitate the use and re-use of mathematical and scientific content on the Web. It is supported for display and storage in PageSeeder (see following).
Allette Systems has not had enough use of the WIRIS editor to endorse its mathematical credentials. However, it seems good and following a straightforward integration with PageSeeder, it was possible to create and edit MathML content with no issues.
