[furcas-discussion] Question regarding re-use strategy for foreach-produced elements

[Uhl, Axel]

Follow-up question: Are transitive, nested foreach-executions all documented by correspondingly nested TextBlock instances? Probably something for our workshop where we discuss the future TextBlocks structures. Anybody have an idea right now?
