明めい示じ範はん囲い符ふ

• 区く切ぎり記き号ごう

  区切り記号 is a general delimiter, while 明示範囲符 specifically marks the end of a scope.

• 終しゅう了りょうタグ

  終了タグ is a closing tag in markup languages, a common example of an explicit scope terminator.

Compound of 明示 (explicit) + 範囲 (scope) + 符 (mark/symbol). A technical term likely coined in computing contexts.
