AI Summary: The task is to generate a formal schema for a 'Pattern Language' by processing several markdown files. This involves defining the core schema and expressing the language as a meta-pattern from 'APL - Home Main.md', mapping three 'Pattern Categories' (Towns, Buildings, Construction) to the schema, and creating 36 'Pattern Sequences' by combining headers and descriptions from 'aplbulltes.md', 'aplsummary.md', and other related files, all structured according to the new schema.
