Sun has also voiced concerns that IBM and Microsoft might charge "tolls" to developers, in the form of royalties on patents, for using existing Web services specifications including the Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL) and Universal Description, Discovery and Integration (UDDI).
Sun's Schwartz said on Wednesday that the company likes those standards, however, "we're very worried about the royalties associated with the use of (those standards). We do not believe in taxing people for use of those standards."
Neither Microsoft nor IBM have formally stated a desire to charge royalties on the standards, which are in part based on patents held by them.

Yet Sun has no problem charging royalties on Java (which they claim is a standard).
