The parsing error seems to be clear enough? There is no bean in the schema type for parameter, hence it can't appear there. As to the schema validation errors, the group appears to be not properly redefined. The way it's redefined is supposed to be a restriction, i.e. you should list a subset of the elements/groups of the group you are redefining. If you want extension, you should reference the group you are redefining in the new group and add the elements you want. Looking at the schemas, the groups are identical in both schemas (with bean element commented out, btw). So, you can just remove the group as a child of redefine.
