Looks like no one ever replied to you Robin.

The answer can be found in 15.7.2 Common attributes

Note that a <filter-primitive-reference> is not an XML ID; instead, a
<filter-primitive-reference> is only meaningful within a given
'filter' element and thus have only local scope. It is legal for the
same <filter-primitive-reference> to appear multiple times within the
same 'filter' element. When referenced, the
<filter-primitive-reference> will use the closest preceding filter
primitive with the given result.

ie. any arbitrary string.
