[Rdfapi-php-interest] Important RdfParser bug and fix

Seems like there I found an error in RdfParser.php. Consider the=20
following RDF:

<?xml version=3D"1.0" encoding=3D"UTF-8" ?>
<rdf:RDF
   xmlns=3D"http://powl.sf.net/SysOnt/0.1#"
   xmlns:rdf=3D"http://www.w3.org/1999/02/22-rdf-syntax-ns#"
   xmlns:xml=3D"http://www.w3.org/XML/1998/namespace"
   xmlns:rdfs=3D"http://www.w3.org/2000/01/rdf-schema#">

<Label ID=3D"Label230">
   <rdfs:label xml:lang=3D"pl"=20
rdf:datatype=3D"http://www.w3.org/2001/XMLSchema#string">Text</rdfs:label=
>
</Label>
</rdf:RDF>

When parsing this snippet the xml:language attribute is then not taken=20
into account since in api/syntax/RdfParser.php in function=20
add_statement_to_model() we have:

        if ($datatype !=3D '') {
            $objobj->setDatatype($datatype);
        }  =20
        else if ($xml_lang !=3D'') {
            $objobj->setLanguage($xml_lang);
        }   =20

the "else" should be removed! So, please change Line 2223 from:

        elseif ($xml_lang !=3D'') {

into

        if ($xml_lang !=3D'') {

and everything should be fine. I'm wondering that nobody had the problem=20
before...

Cheers,
