- Analogy drawn between hierarchical slash-separated URLs and positional parameters in programming languages.
- Introduces matrix syntax in URLs using semicolons to represent named parameters, akin to name-value pairs in procedure calls.
- Discusses relative URLs starting with semicolons for updating or removing parameters, with order considered insignificant.
- Provides examples of how relative matrix URLs should be parsed, including parameter changes and deletions.
- Notes that matrix URI parsing is theoretical and not widely implemented as of 1996-1997.
