I think the maxLength restriction is counted in the number of decoded
bytes not the number of bytes needed for the encoding. Please check
section 4.3.3 of <http://www.w3.org/TR/xmlschema-2/>. (I did run into
this before; perhaps it is worth adding a comment so that we do not
run into this question again - or worse someone "fixes" this later
on.)

Your ObjectIdentifierFragment simply is not an ObjectIdentifier...
