Hi, I found a problem on the file "pjsip\src\pjsip-simple\rpid.c", in the function pjrpid_add_element, line 149. The creation of the id attribute for the XML element "person" is not valid. The string being generated needs to start with a letter or an underscore, as specified on the XML Schema for this attribute. The XML schema for this attribute can be found on http://www.apps.ietf.org/rfc/rfc4479.html, page 26: <xs:attribute name="id" type="xs:ID" use="required"/> According with the definition of the xs:ID (http://www.w3.org/TR/2000/CR-xmlschema-2-20001024/#ID): "The lexical space of ID is the set of all strings that match the NCName production in[Namespaces in XML]." The specification of the NCName is the following: [4] NCName ::= NCNameStartChar NCNameChar* /* An XML Name, minus the ":" */ [5] NCNameChar ::= NameChar - ':' [6] NCNameStartChar ::= Letter | '_' BR, Filipe Figueiredo _________________________________________________________________ Acesse o Portal MSN do seu celular e se mantenha sempre atualizado.
