Unfortunately, i cant provide you the xsd , xml files as those were confidential. However, i can say that the field in question "b" is available in xsd but i didnt see the field in generated avro schema.

<xsd:complexType name="DecodingResponseCT">
xsd:sequence
<xsd:element name="a" type="xsd:string" />
<xsd:element name="b" type="xsd:string" />
<xsd:element name="c" type="xsd:string" />
<xsd:element name="errorMessages" type="ErrorMessagesCT"
minOccurs="0" maxOccurs="1" />
<xsd:element name="e" type="WarningMessagesCT"
minOccurs="0" maxOccurs="1" />
<xsd:element name="f" type="InfoMessagesCT"
minOccurs="0" maxOccurs="1" />
<xsd:element name="g" type="QueryResultCT"
minOccurs="0" maxOccurs="unbounded" />
/xsd:sequence
/xsd:complexType

part of the snippet from generated avsc file

"fields" : [ {
"name" : "a",
"type" : "string",
"source" : "element a"
}, {
"name" : "userId",
"type" : "string",
"source" : "element userId"
}, {
"name" : "c",
"type" : "string",
"source" : "element c"
}, {
"name" : "d",
"type" : [ "null", "string" ],
"source" : "element d"
}, {

Please note, the other fields under the same parent were available in avro schema. Please let me know if you want me to provide any other details.
