John,

You nailed it. With the suggest NEW text, I think that the PCE charter will be clearer

Something like this?

OLD:
The PCE Working Group is chartered to specify the required protocols
so as to enable a Path Computation Element (PCE)-based architecture
for the computation of paths for MPLS and GMPLS Point to Point and
Point to Multi-point Traffic Engineered LSPs. Further, the PCE WG also
handles protocol extensions for new path setup types of Segment
Routing (SR), BIER, and Detnet.

NEW:
The PCE Working Group is chartered to specify the required protocols
to enable a Path Computation Element (PCE)-based architecture
for the computation of paths for MPLS and GMPLS Point to Point and
Point to Multi-point Traffic Engineered LSPs, as well as new path setup
types of Segment Routing (SR), BIER, and Detnet.

As in,

OLD:
In this architecture path computation does not necessarily occur on
the head-end (ingress) LSR, but on some other path computation entity
that may not be physically located on each head-end LSR. The TEAS
Working Group is responsible for defining and extending architectures
for Traffic Engineering (TE) and it is expected that the PCE and TEAS
WGs will work closely together on elements of TE architectures that
utilize PCE.

One is closer than the other? ;-)

I think we can strike “close”.

Essentially, s/Definition/Specification/ (4x), right? My bad on missing this.

Thanks for the additional review and helpful comments,
