91    Through this mechanism, the system can show to the user all documents
92    that share text with the current document.  In the xanalogical storage model,
93    links are not between documents, but individual characters. For example, in the
94    World Wide Web links are between documents, while in the xanalogical storage model
95    links are between individual characters. Each character has a
96    permanent, globally unique identifier. A xanalogical link is shown between
97    any two documents containing the characters that the link connects. Xanalogical links
98    are external and bidirectional.
