Summary0010292: Incorrect ValueRank field value in 1.05.04 base NodeSet
Description

Trying to load 1.05 base nodeSet (https://reference.opcfoundation.org/nodesets/162), one issue is raised with the following part of XML file:

 <UADataType NodeId="i=19311" BrowseName="JsonNetworkMessage" Purpose="ServicesOnly">
    <DisplayName>JsonNetworkMessage</DisplayName>
    <References>
      <Reference ReferenceType="HasSubtype" IsForward="false">i=22</Reference>
    </References>
    <Definition Name="JsonNetworkMessage">
      <Field Name="MessageId" DataType="i=12" />
      <Field Name="MessageType" DataType="i=12" />
      <Field Name="PublisherId" DataType="i=12" />
      <Field Name="WriterGroupName" DataType="i=12" />
      <Field Name="DataSetClassId" DataType="i=12" />
      <Field Name="Messages" DataType="i=22" ValueRank="-2" AllowSubTypes="true" />
    </Definition>
  </UADataType>

Indeed, one field of the structure of a DataType field contains the value -2 as value rank whereas according to the specification, It shall be Scalar (-1) or a fixed rank Array (>=1) (see https://reference.opcfoundation.org/Core/Part3/v105/docs/8.51#_Ref433698626).

Add note to the description for this node in the nodeset to indicate it is here to get "close" but exact serialization requires custom code,
