Attribute describes a dataset or concept attribute with optional textual information, data type, and values.
It can optionally reference a concept corresponding to the attribute values.
The attribute's data type can be specified using a "ref" attribute and optionally formatted using a "format" attribute.
An optional "id" can be provided, which must be unique within the concept, otherwise it's implicitly derived from the referenced concept.

concept xs:QName
optional
A reference to a concept that corresponds to the values
of the attribute. If the attribute specifies a type, then the type
must match the type of the referenced concept. A reference to an
external concept must be of the form
"prefix:other_concept_id", where "prefix" is
the prefix used for the namespace of the external dataset (see XML
namespaces).
id LocalId optional
The id of the concept attribute. This identifier must be
unique within the concept (across attributes and properties). The
id may be omitted if the concept attribute is specified. In that
case, an id is implicity created with value the local name of the
referenced concept. For instance <attribute
concept="unit:currency"/> is equivalent to
<attribute id="currency"
concept="unit:currency"/>
