Subtracts all attributes of subtract from this and returns a matcher that supports those
attributes.
Note that currently it is not possible to remove a single attribute when the this matches the whole namespace - or remove a namespace or attribute when the matcher matches everything. This is a limitation of the current implementation, but may be fixed in the future.
