Can you mention what the main flaws are for Piccolo? I've seen a number
of companies using it, and from what I remember it's also the basis of
the parser used by BEA's NetBeans (now part of Apache, so that may be
changing). Many people would consider BEA's main XML infrastructure
project to be serious work. :-)
Piccolo was considerably faster than the Xerces version in use at the
time it first came out, but the Xerces team seems to have put more of a
focus on performance since then. Recent versions of Xerces look to be
about on a par with Piccolo performance.
