H264 profile-iop explained

Define h264 profile and level from sdp profile level id?

How to determine what restrictions mean? For example, I have profile-type-id: 42801eone that translates to:

enter image description here

How do I associate this with the functions defined in the table here ?

The link above indicates what this Constraint_set0_flag: 1means is a limited base profile. But how to connect the flag with three different NOs (from the table) that differentiate the baseline profile from the profile with the baseline limit?

Update

It is not possible to confirm that the above identification Constrained Baseline profileis correct. Reference (page 306) for this statement:

Decoders conforming to the Constrained Baseline profile at a 
specific level shall be capable of decoding all bitstreams 
in which all of the following are true:

– profile_idc is equal to 66 or constraint_set0_flag is equal to 1,
– constraint_set1_flag is equal to 1, 
– level_idc and constraint_set3_flag represent a level 
less than or equal to the specified level.
