The documentation claims that ixsl:set-style and ixsl:style() are available in Node.js; but I think that these are actually only available in the browser. In the browser, we are dealing with an HTMLElement from the HTML page, which has a style property; but a general Element (as in Node.js) doesn't have a style property.

In fact, attempts to use ixsl:set-style and ixsl:style() in Node.js currently fall over in the code. Using ixsl:set-style results in an error "ReferenceError: Element is not defined" caused by the use of !(elem instanceof Element) in the run time implementation. We should probably replace this with DomUtils.isElement(elem), even if this is only for the browser. Meanwhile, the implementation for ixsl:style() calls window.getComputedStyle(x); which falls over in Node.js because there is no window.

I think we should update the code to produce a run time error if these extensions are used when running in Node.js. Also for other relevant IXSL functions: ixsl:event(), ixsl:location(), ixsl:query-params().
