I don't think that 'sidebar' has much to do with it. The part that is
not working as expected is the 'mysidebar', which is not getting the
'outer' location, nor the 'none' captioning that I get with
placefloat.
setupfloat[mysidebar][leftmargindistance=-.25in,rightmargindistance=-.25in,outer,none]
I swear I used to understand this stuff. I plead old age. Why do I get
two different results from the float placements here:
definefloat[mysidebar][mysidebars]
setupfloat[mysidebar][leftmargindistance=-.25in,rightmargindistance=-.25in,outer,none]
defineframedtext [sidebartext]
