Space Wizard: How to change the title of description

[sbixsbix]

Hi,
I have defined in my content model, a specialized folder type.
ONLY for this type I would like to "override" the "description" title (cm:description).
I have inserted into the web-client-config-custom.xml, this section:
<config evaluator="string-compare" condition="Space Wizards">
   <folder-types>
      <type name="sals:realtyFolders"
        display-id="Realties"
        description="Acquisition/Dismission/Maintenance work on" />
</folder-types>
</config>

and the Advanced Space Wizard works fine until step 3, then I would like to change the "Description" title in "Address", so I have inserted the following block in the same file:

   <config evaluator="node-type" condition="sals:realtyFolders">
        <forms>
           <form>
                <appearance>
                   <field id="cm:name"  />
                   <field id="cm:title" />
                   <field id="cm:description" label="Address" />
                </appearance>
           </form>
        </forms>
   </config>

Without any good result, what am I doing wrong?
Furthermore, is there a way to make the field Description mandatory, without acting on the content model file but only on the web-client config file?

I think the one which you have done is for share
For Explorer it will be something like this

 <config evaluator="node-type" condition="sals:realtyFolders">
      <property-sheet>
         <show-property name="name"/>
         <show-property name="title" display-label-id="title"
                        ignore-if-missing="false" />
         <show-property name="description" display-label="Address"
                        ignore-if-missing="false" component-generator="MultilingualTextAreaGenerator" />
      </property-sheet>
   </config>
