 - ✅ **SAX-based XML parsing** with accurate location tracking for error reporting
 - ✅ **Performance optimizations** - O(1) state/transition lookups, optimized active configuration
 - ✅ **Source field optimization** - Transitions include source state for faster event processing
-- ✅ **Code quality** - Full Credo compliance with proper module aliasing throughout codebase
 
 ### Planned Features
 
 - History states (`<history>`)
 - Internal and targetless transitions
-- Executable content (`<script>`, `<assign>`, `<send>`, `<onentry>`, `<onexit>`, etc.)
+- More executable content (`<script>`, `<assign>`, `<send>`, etc.)
 - Enhanced datamodel support with more expression functions
 - Enhanced validation for complex SCXML constructs
