Hrm. Ignore this email. For some reason, I was getting something else wrong somewhere. For reference, the ? approach works - use-macro="here/skins/?locSkin/pagelayout/macros/?skin", with appropriate functions and tal:defines before it to define locSkin and skin to be single words.

Ok, can someone suggest a better way of saying this:

<span omit-tag="" tal:define="skin here/getSkin ; locSkin here/getLocationSkin ; nonavbar python:1"> <metal:block use-macro="here/skins/${locSkin}/pagelayout/macros/${skin}">

According to my reading of the docs, either use-macro="here/skins/?locSkin/pagelayout/macros/?skin", or the above, should work. Certainly, here/pagelayout/macros/?skin works, but if I put a ?locSkin in the middle of the url, it complains about a list() operation over a non-sequence.

By my reading of the specs, metal attributes should use the tales syntax, and the tales syntax says the above (first) is valid, I think?

Any suggestions/help greatfully accepted ;)
