boil down to function application.  In other words you'll have to write
access functions (SDQL expressions) and apply them whereever you need
them.  If you design your program without relying on DSSSL standard
processing model (walk the tree, find the match, apply) you may be able
to acquire the value once and pass it around to the functions that need
it.  If you're not accustomed to thinking "functionally" (no
side-effects) you may have an adjustment period, but its well worth the
