Since the extra space in front of the XML representation of each child
node is unnecessary according to the SVG 1.1 specification, the attached
V0 patch resolves this issue by removing the offending statement.

The attached V1 patch is a proposal to go a step further by improving
the documentation and using the DOM API to access parts of dom node.

Thanks.  Can you elaborate on what should we consider in order to
decide whether to install V0 or V1?

The V0 patch is the only one required to fix the reported bug.

V1 is just a proposal to improve the doc string and avoid to access dom data using knowledge of the internal representation instead of the dom api.
V1 also include the fix in V0.

I hope it's clearer now.
Thanks
