Flash and Flex both share the flash package.

```auto
flash.accessibility
flash.display
flash.errors
etc...

```

The odd thing is flash uses an additional framework called “fl.” and Flex uses one called “mx.”  
Can anyone shed some light on what differentiates the packages and where their names come from? The “mx.” name for the flex framework is especially perplexing!😏
