Elements – UL Hierarchy

The tree below shows the UL hierarchy of all the entries in the Elements Register (except for the "dummy" "NODE" with a UL concluding 00000000.00000000). "NODE" entries in the Register are shown as "folders" and "LEAF" entries are shown as "files". Note that there could be examples of "LEAF" entries appearing underneath other "LEAF" entries – the hierarchical representation below will represent such situations correctly.

There could be some entries in the tree shown below which do not have a symbol. These entries do not exist in the Register – they have been fabricated in order to make sure that the complete UL hierarchy can be shown correctly (note: such entries will occur where there is a "level skip" in the UL hierarchy in the Register).
