I recently upgraded to XML::LibXML 1.70 and noticed the addition of the ->load_xml method.
When using this in conjunction with the `location` parameter to load an external file it seems to
ignore the InputCallback that was previously working fine with the ->parse_file method.
I have attached a short test case to this e-mail. When the file is read in with ->parse_file a
warning is generated in the InputCallback, however the warning is not triggered with -

>load_xml. Should it be, or am I missing something?
