[PATCH] msxml3: Support IStream in domdoc_transformNodeToObject.

[Daniel Lehman]

> Is it possible to reuse node_transform_node_params() that supports stream output? BSTR case workaround implies that output should already contain BOM.

my other version uses node_transform_node_params and leaves the BOM
that's already there.  i'll send it separately

> Or do you mean node_transform_node_params() is already broken for BSTR output, because it skips BOM?

i didn't think it was broken.  it needs to skip the BOM for other cases
