name of collective of active fragments/documents

While writing a set-theoretic version of the formal semantics for 
theoretical research purposes we needed to refer to the total of active 
fragments and representations of documents as trees. This lead to two 
questions:

1. Why is this not explicitly mentioned as a part of the dynamic
    environment? The formal semantics and the informal semantics don't
    seem to mention it as such but without this information you don't
    have enough information to evaluate an expression, which is what you
    would expect for (the sum of all) environments.

2. How is this usually called? We came up with the name "background
    hedge" ourselves because it is a set of trees with some kind of
    ordering and it is against this background that all expressions are
    evalutated, but we would like to know/use the usual name.
