4. Issues [8:15]
   OData TC Github Issues

   Atomicity requirements and partial execution #2101
   TC reviews the introductory section 11.4.1.1 and proposes changes in the wording. Christof suggests to use the term "isolation" to better describe the effect on other clients. Heiko will update PR Define atomicity #2107 accordingly and also check whether the statement about atomic behavior must be inserted in the sections about (deep) updates of a single entity.

   Nested collections and distinct results #2111
   The desired behavior can be achieved without extending the grammar, by using a custom aggregation method. Aggregation paths can also contain collection-valued segments, see OData-Data-Aggr, section 3.2.1.1. Christof will update the issue accordingly.

   Examples for Scale="floating" #2110
   Heiko will prepare a PR that explicitly lists the three cases

   Precision	IEEE 754	Exponents with lossless representation
   7	32-bit decimal floating point	$-101\le e\le 96$
   16	64-bit decimal floating point	$-398\le e\le 384$
   34	128-bit decimal floating point	$-6143\le e\le 6144$

   and explains the range of values with lossless representation. The IEEE 754 spec cannot be referenced, because it is not freely available.

   How to annotate RequiredProperties during deep insert? #2109
   A capabilities annotation whose target is a canonical collection applies to an entity regardless of how that entity is addressed. The first annotation given in the issue therefore applies to a deep insert of an order item. (Similar for permissions.) Heiko will prepare a PR.
