# :call-seq: deconstruct_keys(array_of_names) → Hash
#
# Returns a hash describing the Attr, to use in pattern matching.

# Valid keys and their values:
# - +name+ → (String) The name of the attribute.
# - +value+ → (String) The value of the attribute.
# - +namespace+ → (Namespace, nil) The Namespace of the attribute, or +nil+ if there is no namespace.
