Hi,

I have an element StaticLayerDataStream referenced in the schema file.
This element can be empty or non-empty in the instance file depending
on circumstances.

<xs:element name="StaticLayerDataStream" type="xs:hexBinary">

Now in the XML instance file, the parser throws an error when it comes
across an empty StaticLayerDataStream element like so:

<StaticLayerDataStream> </StaticLayerDataStream>

I have even tried this

<StaticLayerDataStream/>

but it does not work. Any ideas on how to let the schema identify the
element as being empty sometimes AND non-empty sometimes?

Thanks
John

What is the error message you get from the parser?
<StaticLayerDataStream/> looks prefectly valid.
