Bulk mutation on big schemas through schema model API seems to be slow. For
example, adding an annotation with one appinfo with "source" attribute set to
every element declaration (global and local) of the attached ADT_A01.xsd (plus
all XSDs it references) takes about 150 seconds on a Dell Latitude D600 Laptop
with 2GB of RAM. The number of element declarations being modified is 2683.
