> Project: Daffodil
> Issue Type: Bug

> Performance testing found that the slot removal made in DAFFODIL-1854 caused
> performance degradation, sometimes up to 20% decreases. Profiling found that
> some of this is due to the allocations of the HashMap used for quickly
> looking up elements in the Infoset by QName. We should only allocate hashmaps
> when it's possible an element could be be used in an expression, which should
> improve performance.
