<p class="MsoNormal">Some methods require special design but no name collisions with reserved language words yet. Have some workarounds for method naming in Java and Python that might pertain, this can help.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Example collision: FontStyle has a style field (PLAIN BOLD ITALIC BOLDITALIC) which require some special handling. Ironic that our styling node is somewhat black-holed here. An option is to rename it (e.g. style -> typographyTerm), but
that would require a major attention to conversions. Deferred, probably v4.1 issue, but necessary to consider when crafting X3D4 content.<o:p></o:p></p>
