added line in class Sequence(Collection) solves the bug:
    def extend(self, v): self._subs.extend(v)

I have the same problem, and I tried the solution suggested by Clemens Robbenhaar - but unfortunately it didn't work [ even when I corrected the obvious typo at the end where self._subs.extens(v) should be - IMHO - self._subs.extend(v) ] Could anyone give a helpful solution, please?

<snip>
"The class "List" which does not has the attribute "extend"
is defined in the "ppml.py" (in lib/python/Shared/DC/xml)

Maybe You could try to add such a method to its base class "Sequence",
defined in the same file; e.g. to the class definition:

class Sequence(Collection):

    def __init__(self, v=None):
        if not v: v=[]
        self._subs=v

    def __len__(self): return len(self._subs)

    def append(self, v): self._subs.append(v)

    def value(self, indent):
        return string.join(map(
            lambda v, indent=indent: v.__str__(indent),
            self._subs),'')

append something like:

    def extend(self, v): self._subs.extens(v)
</snip>

XML export is apparently broken for some objects.
Here an example on exporting a ZSQL method:
