You do *not* need to create a private build of WiX to create an extension.
We do so at FireGiant.

I also wanted to add my own attribute to an existing WiX element, so I
studied the BalExtension particularly the behavior of bal:Overridable and
similar attributes.  I may not recall exactly why I decided against this
approach, but I think I concluded that even with a compiler extension, I
would also have to create a private Release build of the Wix toolset.
You could use a Custom Table to add data to the
BootstrapperApplicationData.xml
    <CustomTable Id="CustomData" BootstrapperApplicationData="yes">
      <Column Id="MyData" Type="string" Category="Identifier"
PrimaryKey="yes"/>
      <Row>
        <Data Column="Tag">$(var.someData)</Data>
      </Row>
    </CustomTable>
Or use a compiler extension to add a child to a Features element.  Look at
any of the wix extensions source code for something similar to this.

Hello,

I would like to be able to define/use a custom attribute of the Feature
element; e.g.

<Feature
    atr1="Some data"
...

As far as I could figure out, you need to create an extension to enable
this.
I have seen/studied guides/tutorials on the net, but those talk about adding
custom elements, not extending predefined ones.
I don't need this attribute to influence the resulting MSI in any way, its
purpose wold be purely administrative.
Is this possible?
Any pointers as to how to achieve it?

Regards,
János
