The UnboundID SCIM SDK is a library that may be used to interact with various
types of SCIM-enabled endpoints (such as the UnboundID server products) to
perform lightweight, cloud-based identity management via the SCIM Protocol.
See http://www.simplecloud.info for more information.

/**
* This class represents a System for Cross-Domain Identity Management (SCIM)
* attribute. Attributes are categorized as either single-valued or
* multi-valued. This class allows for the following kinds of attributes.
*
*
* - Simple type (String, Boolean, DateTime, Integer or Binary).
* An example is the 'userName' attribute in the core schema.
*
* - Complex type. An example is the 'name' attribute in the core
* schema.
*
* - Multi-valued simple type. Represented using multi-valued complex values,
* because the values may have 'type' and 'primary' sub-attributes to
* distinguish each primitive value. Examples of this are the 'emails' and
* 'photos' attributes in the core schema.
*
* - Multi-valued complex type. An examples is the 'addresses' attribute in
* the core schema.
