All attributes in Python are dynamically attachable.
>>> class Parrot:
... pass
...
>>> p = Parrot()
>>> hasattr(p, "plumage")
False
>>> p.plumage = "beautiful red"
>>> p.plumage
'beautiful red'

Have you considered a simpler class like this?
class Thing(object):
def __init__(self, value="something important"):
self.text = TxtAttr(value)
t2 = Thing("another string")
Then, instead of writing t2.props["text"].value (four lookups) you would
just write t2.text (two lookups).
