{{Aisle/Feature
|Summmary=Being a source-based editor, syntax highlighting is crucial for the ease of use of Aisle. The emphasis should be on "localizable content", and there should be strong indications of format errors. There should *not* be auto-correction of potential errors.

We'll want a comprehensive support of existing formats, and extensibility for future formats.
