I'm not sure about this statement "The xml of the gnumeric spreadsheet format seems superior (more compact) compared to the xml of the calc module," however export seems like a possible addition, so status: NEW seems fine.

What's the use case for Gnumeric XML export? Are there any large companies or groups standardizing on Gnumeric XML?

Gnumeric:

      <gnm:Cells>
        <gnm:Cell Row="0" Col="0" ValueType="60">test</gnm:Cell>
        <gnm:Cell Row="0" Col="1" ValueType="40">10</gnm:Cell>
        <gnm:Cell Row="0" Col="2" ValueType="40">20</gnm:Cell>
        <gnm:Cell Row="1" Col="0">=sum(B1*C1)</gnm:Cell>
      </gnm:Cells>

Calc:

         <table:table table:name="Sheet1" table:style-name="ta1" table:print="false">
            <table:table-column table:style-name="co1" table:number-columns-repeated="3"
                                table:default-cell-style-name="Default"/>
            <table:table-row table:style-name="ro1">
               <table:table-cell office:value-type="string">
                  <text:p>test</text:p>
               </table:table-cell>
               <table:table-cell office:value-type="float" office:value="10">
                  <text:p>10</text:p>
               </table:table-cell>
               <table:table-cell office:value-type="float" office:value="20">
                  <text:p>20</text:p>
               </table:table-cell>
            </table:table-row>
            <table:table-row table:style-name="ro1">
               <table:table-cell table:formula="of:=SUM([.B1]*[.C1])" office:value-type="float"
                                 office:value="200">
                  <text:p>200</text:p>
               </table:table-cell>
               <table:table-cell table:number-columns-repeated="2"/>
            </table:table-row>
         </table:table>

Those that seek to use the alternative xml of gnumeric, for example for creation of an xml database.

Commercial use, by definition, not necessarily disclosed to public domain.

Gnumeric XML is a quite bad format as it changes regularly. We are going to have an initial import in 5.1 but I doubt that we will ever implement a gnumeric export.
