I can get formal and informal figures to float to the top of the page using the methods described in DbXsl TCG p. 296 and Antenna House Formatter. And I can get them to float right and left by wrapping them in a sidebar, as on page 232. But when I try to float them left or right on their own, I get an error message, "AHFCmd :WARNING: Invalid property value: end-indent="0pt + + 0pt". Apparently, the width does not reach the floater template, and there does not seem to be a dbfo for figure-width, as there is for sidebars.
Is it expected that right and left floats should always be wrapped in a sidebar or margin note, or should it be possible to float objects independently of a sidebar? Using the Custom Side Float example on p. 236, I think I could add that functionality to formal objects, but I don't want to reinvent the wheel. I see that AHF has extensions that allow, for example, floats to the bottom of the page using axf:float="after", and I can get that to work by manually editing the fo. For axf:float="left", it even computes the width from the enclosed imagedata width. I might undertake adding that to my stylesheet customization as an alternative by customizing the floater template to recognize additional floatstyles, like axf-after, for example.
