Subtracts all attributes of subtract from matcher and returns
a matcher that supports those attributes.
Note that currently it is not possible to remove a single
attribute when the matcher 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.
