This is a style of modeling the mixes text and diagrams in one document with cross-references. Inspired by DonaldKnuth's LiterateProgramming. Introduce(?) by Jim Arlow and Ila Neustadt, In their "Enterprise Patterns and MDA..." published by Addison-Wesley in 2003. Described and motivated on page 98. There book illustrates the style and I find it quite understandable as a result.
