Hello, \setupurl[color=blue] does not work in mkiv again. Also, please look how I use \useURL and \goto to typeset the link. Is there a way do it less verbose?

The essential distinguishing feature of this category of system is the fact that a conceptual model can be formulated as a set of differential equations, possibly augmented with a set of algebraic equations\footnote{\goto{\hyphenatedurl{http://en.wikipedia.org/wiki/Differential_algebraic_equation}}[url(http://en.wikipedia.org/wiki/Differential_algebraic_equation)]}. For the most part, such models emerge from a deductive process that has its basis in physical laws that are known to govern the behaviour we seek to explore, that is, the behaviour of the SUI. \stoptext
