Whenever you say "XML", you implicitly say "text", and for all programming
systems that aren't dealing with all data as strings, some conversion between
binary and string has to be done. You ought to know all the consequences
of passing binary data between systems, and the trade-off between the
basic choices.

Binding between XML Schema types and, say, Java types is not a 100% fit.
But it is amply sufficient for real-world applications. Having all X[A-Z]+
systems adhere to this common typing system has the benefit that
a conversion library between XML and binary can be re-used.
