i get this question from time to time so here is the list:
1. xpp3 parser accepts all valid XML input except if it contains
    internal DTD subset (it is currently ignored)
2. parser is more liberal in accepting unicode characters
    and currently is essentially accepting what is defined in XML 1.1 and not XML 1.0
3. it does not do detection of input stream encoding and relies on user to
    declare it correctly as setInput parameter (np problem if you are using ReadeR)
4. it is well tested but stable version is relatively new so beware that there can be
    some undiscovered bugs (this is open source project so patches are gratefully accepted
    and your contribution will be acknowledged and appreciated by other users :-))

it is not very difficult to fix those problems and i will eventually do this
when i have few weeks of free time (there is even first incomplete stab on
DTD parsing and internal entities on source code) with ultimate goal to pass
OASIS conformance tests for XML 1.0 non-validating parser but i do not see happening
it too soon :-)

thanks,

alek
