Also, the following
OOO_IMPORTER( XMLMathSettingsImportOOO,
"com.sun.star.comp.Math.XMLSettingsImporter",
"com.sun.star.comp.Math.XMLOasisSettingsImporter" )
was in the xof.component file, but was not listed in the factory class.
I fixed that, but it means we might see some differences in import
behaviour when reading math documents
