Original GitHub issue: https://github.com/semver/semver/issues/568

Build metadata MAY be denoted by appending a plus sign and a series of dot separated identifiers
immediately following the patch or pre-release version. Identifiers MUST comprise only ASCII
alphanumerics and hyphen [0-9A-Za-z-]. Identifiers MUST NOT be empty. Build metadata MUST be ignored
when determining version precedence. Thus two versions that differ only in the build metadata, have the
same precedence. Examples: 1.0.0-alpha+001, 1.0.0+20130313144700, 1.0.0-beta+exp.sha.5114f85.

The explanation that

two versions that differ only in the build metadata, have the same precedence

is followed by examples that differ in build metadata, but do not have same precedence, because the first and third examples are pre-release versions and thus have lower precedence.

I suggest replacing the examples that include both pre-release and build metadata information with clearer examples that only have build metadata,

I don't think those examples were intended to be limited to just the last sentence. They are just a few random samples of build meta usage.

Additionally, 1.0.0-beta+exp.sha.5114f85 does not meet the bnf specification. Specifically, the build identifier 5114f85 is neither alphanumeric identifier nor digits.

Also, 1.0.0+21AF26D3----117B344092BD does not meet the bnf specification. Specifically, the build identifier 117B344092BD is neither alphanumeric identifier nor digits.

@chonton commented on GitHub (May 15, 2023): Additionally, **1.0.0-beta+exp.sha.5114f85** does not meet the bnf specification. Specifically, the **build identifier** `5114f85` is neither **alphanumeric identifier** nor **digits**. Also, **1.0.0+21AF26D3----117B344092BD** does not meet the bnf specification.

@chonton, specifically which character(s) in those strings are neither alpha or numeric? Were they encoded incorrectly?

I don't see the problem.

I got it wrong. The build identifier cannot be digits, since it does not consist only of digit. It can be alphanumeric identifier. What confused me is that I cannot determine the difference between digits and alphanumeric identifier until the next '.' or end of input.
