Replace text in 3.4.1.2.1 as follows:
Replace

“
As stated in Table 3-2, the field shall provide for the textual description of the bits read, according
to the syntax used in ISO/IEC 14496. I.e., every sophisticated ISO/IEC 14496 syntax element that is being
constructed from other syntax element has to be broken down recursively to primitive syntax elements that
cannot be broken down any further.

E.g., there would be no(!) value Transform2D. Instead, every node would have to be broken down
by its fields. The fields in turn would have to be broken down further (one exception is formed by fields of type
SFBool, which cannot be broken down further). I.e., a field of type SFFloat would have to be broken down
recursively until the mantissa and exponent level is reached.

Change subclause numbers after 7.3.1.2.4.8 as follows:
There are three subclauses for Test #9,Test#10 and Test#11 that need to have respective subclause
numbers changed to 7.3.1.2.4.9, 7.3.1.2.4.10, 7.3.1.2.4.11 .

Fix reference in 7.2.2.1.2 as follows:
Line 4 of Table 7-1 has a reference that should be to Test#11, (which by above changed to) 7.3.1.2.4.11


Replace Table 3-4 in 3.4.3.1 with the following table to include new bitstreams:

10. BIFS-Anim: integer animation anim2
(There are no native nodes that have integer
animatable fields. This example uses a PROTO. It's the
only way to do integer animation and so only one
example is provided for this feature).
11. BIFS-Anim: several fields in the same node anim-rect, anim-box
12. BIFS-Anim: several nodes anim-simple, anim-box
13. BIFS-Anim: skip frame No test provided. skipFrame is available for
compatibility with FBA, but it is not used in BIFS-anim.
14. BIFS-Anim: switch of a node (isActive mask) anim1, anim2
15. BIFS-Anim: random access true anim-box1, anim-box2
(any animation other than ANIM 5/anim1 or ANIM
6/anim2)
16. BIFS-Anim: random access false Anim1, anim2
