The pattern is constructed using alternation to match each distinct type:
1. XML tags: Carefully escaped angle brackets and attributes
2. Code blocks: Escaped backticks (both triple and single)
3. Math expressions: Escaped special characters in formulas
4. Special identifiers: @ followed by specific format
5. Release versions: Specific version number patterns
6. Custom protocols: URL patterns with escaped special characters
7. JSON-like objects: Escaped braces and content
8. Formatted IDs: Square bracket patterns with specific formats

Each special character that has meaning in regex (like ., [, ], (, ), {, }, +, *, ?) is properly escaped with a backslash. The pattern uses alternation (|) to match any one of these specific patterns.
