93      * DConfigBean.getXpaths(). However, when the studio calls getDConfigBean
94      * to create those beans, they pass us an absolute xpath. (This is vague
95      * in JSR-88 1.0, but was clarified as a violation of JSR-88 1.1.)
96      *
97      * Anyway, this method allows us at runtime to determine what relative path
98      * we most likely passed them that caused the call to getDConfigBean now
99      * being processed. We need the relative xpath because that is how our
100      * factories are indexed.
