It does indeed -- my apologies for not reading the annotations
more carefully! I missed that one in particular. Okay, you've
dragged me, kicking and screaming, to agree that the actual,
published design intent of XML is to provide a "data
Thanks to Fredrik for the link he included (elsewhere
JSON looks like a notable improvement over XML for data
objects that are more fine-grained (higher ratio of markup to
non-markup -- e.g., most relational data sets, RDF, etc.)
than those at the more traditional "document" end of the
spectrum (less markup, more text).
The latter types of data objects are the ones I happen to believe
are in the sweet spot of XML's design, regardless of its designers'
more sweeping pronouncements (and hopes, no doubt).
I should note that I have to deal with XML a lot, but always
