Re: [ANN] data.xml 0.2.0-alpha1

Hi Francis, first off: if you can afford it, I'd recommend working with the 0.2.0 series, as the 0.1.0 namespace api is legacy. In the 0.2.0 series, the mapping of keyword prefix to xmlns is unique and fixed, so names are always parsed as keywords (though QName instances still are permitted for e

Re: [ANN] data.xml 0.2.0-alpha1

Sorry for the late response, I had to finish 0.2.0-alpha2, in order to present you with the final API for constructing qnames. Please upgrade. ​::can/mqMessageHeader is a purely syntactic shorthand, which gets expanded by the reader to whatever 'can aliases to in the current namespace. Apparently
