@ignore
The @ignore tag tells documentation-generating tooling to leave the decorated element out of its output entirely, as if it did not exist. This is stronger than @internal, which still documents an element but flags it as an implementation detail not meant for consumers: @ignore removes it from the generated documentation altogether, which is useful for scaffolding, deprecated leftovers, or helpers that would only confuse readers of the public reference.
Parsing an @ignore tag produces an IgnoreTag instance. Being a pure marker, it adds nothing beyond the $name and optional $description every Tag already carries.
@ignore is still part of phpDocumentor's current tag reference and is not deprecated — phpDocumentor tag reference. It is parsed here for compatibility with classic-style docblocks.
