Ok, I answered #1 myself by opening the html file and finding the styles in the head area....and it appears to correspond with the xml files for the styles, so that leaves #2 above. What if I did not have the files you provided in #1, and just had the Preset Manager. How does WA see it being used beyond generating the images and XML? Again, outside of using XSLT to generate HTML from the XML, is there another step using the extensions that I am not aware of?
Thanks,
Robert
