UAF13 — Standards need to be decomposable

View specification for <<Standards>> elements do not allow for directed composition into other <<Standards>>. Specification for <<Standards>> elements do not specify a part property.
This is needed because many ConformsTo relationships conform to only a specific part of a standard, rather than the entire standard. Traceability is enhanced by allowing for a UAF Element to ConformTo a standard at a lower level than the parent.
