An DiagnosticInfo value is encoded as an xs:complexType with the following XML schema:

<xs:complexType name="DiagnosticInfo">


<xs:element name="SymbolicId" type="xs:int" minOccurs="0" />

<xs:element name="NamespaceUri" type="xs:int" minOccurs="0" />

<xs:element name="Locale" type="xs:int" minOccurs="0/>

<xs:element name="LocalizedText" type="xs:int" minOccurs="0/>

<xs:element name="AdditionalInfo" type="xs:string" minOccurs="0"/>

<xs:element name="InnerStatusCode" type="tns:StatusCode"

minOccurs="0" />

<xs:element name="InnerDiagnosticInfo" type="tns:DiagnosticInfo"

minOccurs="0" />



DiagnosticInfo allows unlimited nesting which could result in stack overflow errors even if the message size is less than the maximum allowed. Decoders shall support at least 100 nesting levels. Decoders shall report an error if the number of nesting levels exceeds what it supports.
