I think higher-order-functions are becoming a core part of XQuery and XSLT; we shouldn't encourage the mindset that they should be avoided because not all implementations will support them. I therefore propose dropping this as an optional feature; the relevant capabilities should become a core part of the language in 4.0, supported by all conformant implementations.
