>          Issue Type: Bug
>          Components: xml/om
>    Affects Versions: 1.7.0

> in axiom_element_add_attribute, the attribute is added to the hash of attributes in om_element->attributes
> based on the name (axutil_qname_to_string).
> If an attribute with the same name is already in the hash, that entry is overwritten and thus, will never be freed.
> This seems to be the case always if several xml nodes have the same namespace - the attribute value itself is not used there, or are 
> we just talking namespace attributes here?
> I don't even begin to understand what the role of the attributes is, and what happes, if the attributes are stored with different names or such.
> For the moment, I will try to create two hashes, one for the attributes that are used, and one for the attributes that just have to be freed. Of course, a list would be enough for the latter.
