For a given profile, removes a value from an attribute selected with its version ID. Permits the removal of default and custom attributes.
Profiles and attributes
Profiles are created on account level whereas attributes and tags are defined on sections. They are then set on profiles on section level as well.
Even though default attributes like First Name or Email have the same names across sections, setting their value on a profile in one section will not affect their values in other sections. Custom attributes and tags created in one section can only set on profiles on that section level.
