The current implementation of NSHTMLWriter only supports a single shadow. This shadow is an NSShadow instance set with attribute key NSShadowAttributeName.
NSHTMLWriter maps those core text attributes to their CSS counterparts for display in e.g. UITextView. CSS supports multiple shadows, e.g.
<p style="text-shadow:0.2em 0.5em 0.1em #600,
-0.3em 0.1em 0.1em #060,
0.4em -0.3em 0.1em #006">Multiple Shadows</p>
My enhancement request is to allow the NSShadowAttributeName to also be an array of multiple NSShadow instances. Those would simply be transferred to the css style for the span.
This enhancement would make shadows work the same in HTML and CoreText.
