TaxonomyTermGroupDefinition misses [ExpectRequired] for Name property

[SubPointSupport]

Current definition looks as following:

        [ExpectValidation]
        [DataMember]
        [IdentityKey]
        public string Name { get; set; }

Name property is a required one, should have [ExpectRequired] attribute.

        [ExpectValidation]
        [ExpectRequired]
        [DataMember]
        [IdentityKey]
        public string Name { get; set; }
