Suppress/Set prefix for id of xforms controls?

Hi there,

in former versions I was able to do something like

   <xforms:input ref="remarks/@quality" id="remark-quality"/>

which yielded something like

    <span id="remark-quality" class="xforms-control xforms-input">
        <input id="remark-quality≡xforms-input-1" class="xforms-input-input" type="text" value="" name="remark-quality≡xforms-input-1">
    </span>

Since I'm using Orbeon CE 4.8 there seems to be a slight change in behaviour:

    <span id="xf-10≡xf-25≡remark-quality" class="xforms-control xforms-input">
        <input id="xf-10≡xf-25≡remark-quality" class="xforms-input-input" type="text" value="" name="xf-10≡xf-25≡remark-quality">
    </span>

Obviously the modified id is rather useless and can't be predicted outside of orbeon.

How can I return to the old behaviour which used the defined id without any computed prefix?
Though I think it is generally a good and valueable idea to make the fields unique I think there should at least be a choice to disable it on some controls or for a complete form: If one defines an id it's very reasonable to argue it is going to be used for any purpose - e.g. for styling.
It seems to me that an id has to be unique per definitionem - so anybody who violates this rule is on his own.

Regards,

Jens
