I thought "" was also used to indicate the no-namespace namespace, but don't see any references offhand. Still, it's probably safest to make it work both ways.
Somehow the elements you're trying to marshal appear to have a namespace set. If you want to marshal them as though they were not in any namespace you can modify your own version of the DomElementMapper/DomMapperBase code to always use the nonamespace index (which will always be 0) when writing elements and attributes out. You can also go through the DOM tree and set the namespaces to null (I think it's null for DOM - you should check what the DOM docs say).
for testing purposes i printed out the namespace (uri/prefix) of all
elements which were passed to DomElementMapper.marshalElement... they
were all null. i think the problem is that with a "null" namespace
uri/prefix, DomElementMapper uses the namespace index -1, which causes
the error i described. looking at the method findNamespaceIndex in DomMapperBase, if my
uris/prefixes all would be "" (the empty string) i would get what i
wanted (index 0). i am not quite sure what to conclude. does the empty string mean no
namespace for DOM? or does the DomElementMapper misinterpret uri/prefix
set to null?

That means that DomMapperBase.findNamespaceIndex() should be changed to treat a null URI as equivalent to "", and the first line should probably be changed from:
if ("".equals(prefix) && "".equals(uri)) {to
if (("".equals(prefix) || prefix == null) && ("".equals(uri) || uri == null)) {
