PageItem.applyEffect(LiveEffectXML)

I've been admiring this thread for a while. I appologise if the connection has already been made (particuarly to ten_a) - I've not seen it though; I was googling for more info on the topic, and came this post in Japanese where 投稿者: ten_a shares some of their own live effect code:

I've tested most of them, and they were grand!

This is a great thread, I was following moluapple's method through an uncompressed AI file when I noticed that these Live Effects look like siblings to what I optimistically hope might be other accessible things. In my file, the Stroke Offset effect shows up mixed in with Stroke and Fill effects:

The format looks very similar too -- moluapple's RegExp picks up "Adobe Stroke Offset" which looks to be "Stroke Style Filter" in the effect above. I'm curious if strokes and fills could be accessed as LiveEffects and if what we're looking at is how the Appearance panel is handled. Would it be possible to access a stroke through this method then use PageItem.tag to keep track of multiple strokes? I don't know anything about C++, but I wondered if the way this worked was through the AILiveEffectSuite:

If so, would that mean that a script could potentially have access via app.sendScriptMessage? Or am I completely out in left field on this?

They may be SVG filter?
