Isomorphic and non-isomorphic element mapping for PL/I
Table 1 and Figure 1 are examples of
isomorphic structures (an XML instance document and a PL/I data structure)
and both have isomorphic element mapping.

Table 2 and Figure 2 are examples of
non-isomorphic structures (an XML instance document and a PL/I data structure)
have isomorphic subsets and display isomorphic element mapping.
