Empty Content Element Declaration Problem

Hi,

One of the elements in my XML document has decimal number values (e.g. 1.234, 56.1, etc.). However, it may also contain the value "N/A" or value of empty string.

e.g. the possible values of this element are:
1. <VALUE>122.33</VALUE>
2. <VALUE>N/A</VALUE>
3. <VALUE></VALUE>

I am writing a XML Schema for this XML, and I don't have any idea of how to write the schema for the element I mentioned above. I've tried many different kinds of syntax but still failed when I validated my XML using the schema I wrote (I am using the validator of the XMLSpy 4).

Pls give me some guidances and thank you very much.

Billy
