    Using WebMethods, Inc Developer tool to create a wsdl for a flow service. Try to use .NET wsdl utility to create a C# proxy, but get the errors below. Support person at WebMethods, Inc. says it is a bug in wsdl.exe. I have included the text of the wsdl generated by WebMethods along with the response from WebMethods support. I appreciate any assistance

    If you would like more help, please type "wsdl /?".

    WebMethods support response:
    From my investigation, I have found that this is a .NET bug. Please find
    below the explaination:
    In a WSDL file schema section the element "name" attribute is defined
    as an "NCName" in the XSD Specification[6].

    An NSName[4] has the following production defined in the XSD Spec[7]:
    NCName ::= (Letter | '_') (NCNameChar)*
    NCNameChar ::= Letter|Digit|'.'|'-'|'_'|CombiningChar|Extender

    ..NET seems to think that a "x003A" sequence in a WSDL file element
    "name" attribute has a ':' because it is the hex number of a ':'
    character[3], meaning it thinks the text is "rsi_:_OfficerName" which
    _would_ be illegal if the file really had "rsi_:_OfficerName" in it.
    This character sequence is part of an NSName[6] value, which allows a
    value of "x003A" to mean an element named "x003A".

    The XML Specification is very clear in how one should embed a Hex
    character definition in an XML file [5]. It is not the "x003A"
    sequence, but the entity reference "&#x003A".
