Question about IdResolver.getElementById()

[Yang Yu]

In org.apache.xml.security.utils.IdResolver.getElementById(Document doc,
String id), I'm wondering why it's necessary to do a exhaustive search by
calling:

result = IdResolver.getElementBySearching(doc, id);

Do you see any harm if I comment out this line? Because I notice that the
Element is always found by the first call:

Element result = IdResolver.getElementByIdType(doc, id);

Thanks,
Yang
