Apologies if this is a FAQ -- I'm in mid-workshop. I *think* oXygen already does what I want, but I can't seem to figure out how to get it to. I want whitespace to be normalized in <l>, <p>, and <head> elements when I choose format-and-indent. In the Preferences "Editor / Format / XML" pane, in the "Element Spacing" section, I've added //l //p //head to the "Default space" tab, and made sure they are not listed in the "Preserve space" tab. But either with or without an <?xml-stylesheet?> PI to a CSS file, and whether or not "Schema aware format and indent" is checked, oXygen never strips off my leading or trailing whitespace. Any thoughts? Oh ... it just occured to me: I've scanned the help pages, and the decision about whether to normalize space or not seems to be based more on CSS than on those preferences; could the default oXygen CSS stylesheet (for TEI, of course :-) by messing me up, here?
