Certainly. Woven uses / rather than . as the submodel name separator. 
So simply do this:

<span model="object/title" view="Text" />

/ is used rather than . because / can indicate any method of accessing 
a conceptual child object, whether it occurs by attribute access, 
dictionary or list lookup, or method call; it's up to the IModel 
adapter to decide how to access children. I believe this is covered in 
the "Model in Depth" section of the documentation.

Hope that helps!
