There is no mechanism to perform comparisons of node sets for equality in the same manner one would for mathematical sets. For instance I can't say a node-set containing (A, B, C) is equivalent to a nodeset containing (B, C, A)

Dates are probably the only types requested with any sort of frequency to establish a trend. Funny enough, adding XSD dates may not satisfy some of our end users who expect to be able to use dates in the format from regular usage (e.g. MM-DD-YYYY or DD/MM/YYYY) and may balk at the ISO 8601 format used by XSD (YYYY-MM-DD)
