Oh, okay.  Just groked src and looks like it is a D2 only thing.  Do you happen to know
what the derivation of the word "range" with respect to streams is?  I haven't come
across it before used in this context.

Yes seems that way; my question apparently asked upon D1 knowledge only.

Re SAX, it easy enough to get James Clark's Expat 'C' parser happening with D.
That has an event-based API.  Perhaps all the std D library needs do is wrap this.
Whilst it's open source, dunno about the specific licensing issues though.
