2.1.1607 Part 1 Section, adj (Shape Adjust)

a.   The standard is unclear on what the @idx attribute is a reference to.

The @idx is an index to the list of shape adjust guides defined for the parent shape. These guides are listed under the avLst element in the shape definitions, defined in the preset shape geometries electronic addenda of Annex D.

b.   The standard is unclear on the types of values acceptable in the @val attribute.

If the adj element refers to a shape adjust handle based on rotation, the @val attribute accepts values in degrees.
