Restrictions on the value of "Private-Network-Access-Name"

[goto-bus-stop]

In https://wicg.github.io/private-network-access/#permission-prompt, the spec currently says:

Private-Network-Access-Name should be a valid name which is a string that matches the [ECMAScript] regexp /^[a-z0-9_-.]+$/. 248 is the maximum number of UTF-8 code units in the name.

The regex /^[a-z0-9_-.]+$/ suggests only lowercase letters, digits, ., _, and - are allowed, so no spaces or "special characters" or non-English alphabets. Elsewhere in the spec though, examples do not follow this restriction.

• The example immediately above contains spaces: Private-Network-Access-Name: "My Smart Toothbrush" (i'm not sure the quotes here are intended to be part of the value or to delimit the value)
• The Mixed Content section lists an example with an apostrophe: Private-Network-Access-Name: userA’s MegaCorp device

What should we make of this?
#119 added this restriction. Is it just the case that examples were not updated to match this new restriction? Should I open a PR to update the examples? 😄

If there is to be a restriction we should also rephrase it to not rely on ECMAScript regular expressions. This looks simple enough that it can be expressed in terms of terms defined in the Infra Standard, which is also much more likely how it will eventually be implemented.
