Interesting first draft. Could you relate what comprises your actual
workflow for achieving this? For those of us less familiar with
animation the technical issues and accomplishments are less apparent.

Well, here's the quick version.
1) New IRTC topic.
2) Can I come up with a new bell & whistle or special effect-- in this case
a new motion file for my existing characters-- that will enable telling a
story along the lines of the new topic?
3) Tinker with the capability of the system-- here being trying to get a
motion file that made a really cool (IMNSHO ) walk cycle to also do a
"dance cycle" without destroying the original capability.
4) When there's a draft that is either wildly impressive or funny, post it
to p.b.a.
Here's a long version.
I've got a system set up so that I can use "motion" files and "character"
files interchangeably. The character file could be CSG, a blob, or a mesh:
the joints are rotated by transforms created in the motion file. It was a
lot of work to get a system to this state. So now I can just make a few
changes to the feet and turn a cool walk cycle into a lame dance cycle. (Ah
well, this wasn't actually longer...)

I can imagine. Do you use some form of "bones" to intermediate between
the character definition and the motion definition?

Sort of. In povray, we're forced to (get to) use transforms. You may then
"transform" a point used in the computation of a spline mesh, transform a
cylinder in CSG, or transform a component of a blob.
Here are some snippets from the most basic version which I released several
years ago:
#declare rforearmobj=cylinder{0,rwristpt-relbowpt,1}
....
#declare rforearmtrans=transform{rotate relbowang translate
relbowpt-rshouldpvt transform{rhumerustrans}}
....
object{rforearmobj transform{rforearmtrans}}
