Technical notes

In the class BrailleDisplayGesture in braille.py we have:

#: Compiled regular expression to match an identifier including an optional model name
#: The model name should be an alphanumeric string without spaces.
#: @type: RegexObject
ID_PARTS_REGEX = re.compile(r"br\((\w+)(?:\.(\w+))?\):([\w+]+)", re.U)

And see also the documentation of _get_model method.

Both indicate that this means that the model names should be an alphanumeric string without space. Given the implementation with \w, it can only contain letters and digits as well as underscore. Thus, "b.note" is not allowed since it contains a dot.
