It looks useful. You'll probably need to change your error
handling,
though. I appeciate that you're giving your users options,
but part of
PEAR is a unified error handling mechanism. For PHP5
packages this is
PEAR_Exception. PHP5 packages should not be returning
PEAR_Errors. In
addition, I'm not sure why you have an option to return
errors as
XML... I suppose this couls allow for directly passing
errors back to
some kind of webservice or XML handler directly but this
doesn't
really belong in the package itself, especially since it's
causing
extra code to be added for each error. I suggest you change
your
package to *only* throw exceptions and to allow excpeptions
to bubble
up in places where you're doing no real error handling. If
a user
wants to create an XML error they can add their own
exception handler
around calls to this package.

In addition, you should really create a real PEAR proposal
(which
requires a PEAR account). This will allow us to keep track
of what's
been suggested and done.

As justin mentions I suggest you create a proposal on PePr
(link is in 
the manual). I'm pretty sure the package will be
interesting to many

What's about sql2xml [1]? This package can complete or
replace it at
some point. The goal is pretty much the same.

Did you look at sql2xml? Or contact Christian?
