As I interpret the original post, the desire is to produce one transformation from a set of alternates, based on the value of one or more parameters supplied to the stylesheet. Hence, a common entry point followed by a "branch" to one or another alternative. The poster wants, I believe, to control the logic of this branching via Javascript.

I don't see where Javascript is necessary for this, and I suspect that the original poster is comfortable with Javascript and unfamiliar with XSLT, hence April's desire to control the branching with Javascript.

Could someone explain 'branching logic'?
