Given that, a possible path forward might be to define a VariableFontStyle node that is similar to FontStyle that also includes field definitions.</div>

<div style="direction: ltr;">They are pretty common now.</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">They would require in effect an n-dimensional style.</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">They may be not too hard to support. The difficulty may be mostly in designing fields for n axes and axes values.</div>
