Hi all!

It's interesting that all the tools I've looked at have a hard time
distinguishing between misspellings of attributes and user-defined
attributes.

Given that, and the need to keep the SG15 backlog populated, I have marked
a paper on the subject for review, though I believe I just missed the
filing deadline. It might be officially published in the April mailing.

Here is the paper: https://isocpp.org/files/papers/P2565R0.pdf

Here is the abstract:

While the standard supports vendor-provided and otherwise user-defined
attributes in C++, actual use of nonstandard attributes while preventing
trivial misspellings is a challenge. In particular, diagnostics in
compilers used to prevent misspellings of standard and well-known
attributes will reject attributes provided for other contexts, including
attributes used to support other compilers. This document explores how this
problem presents itself in practice and proposes a potential attribute
declaration syntax to address the problem.
