But I think it better to think of xsl:choose in the mathematical sense, e.g. A := f(x) 0 when x <= 1 17 when x <= 7 A(x - 1) . A(x - 2) when x^2 + 1 is prime 31x / 7 otherwise That is, I prefer to think of XSLT as a functional language in which one is describing the end result rather than as a procedural language with loops and returns. There's no concept of an "early return" from a mathematical function, nor from an XSLT one.
