How to make some string fields with unique value

[Nikola Milanov]

Hi,
I try to make some string fields unique describe in this page: Here
I'm trying to make uniqueness to these fields: Device Name, Serial number, Brand and Model of all Physical devices.
This is the code I use (this is only for 2 fields - Name and Serial number):

        <classes>
                <class id="PhysicalDevice" _delta="must_exist">
        <properties>
        <uniqueness_rules>
          <rule id="functionalci_name" _delta="define">
            <attributes>
              <attribute id="name"/>
            </attributes>
          </rule>
          <rule id="phisicaldevice_serialnumber" _delta="define">
            <attributes>
              <attribute id="serialnumber"/>
            </attributes>
          </rule>
        </uniqueness_rules>
      </properties>

but when I try to update code via Toolkit it doesn't do anything.
What I did wrong or am I miss something?

Thanks,
Nikola

Although incomplete, the start seems okay?

Hi Jeffrey,
Should I put and lines in dictionary section?

Perhaps share your entire code.

Hi Jeffrey,
I think I found my mistake. I'll try and if I have some more questions, I'll write again.
