stereotype is an extension of the vocabulary of the UML, allowing you to create new kinds of building blocks similar
to existing ones but specific to your problem. Graphically, a stereotype is rendered as a name enclosed by guillemets ( French quotation marks of the form
?? ), placed above the name of another element.
模式化是UML词汇表的扩展，允许你创建与已有的构建块相类似，但专门针对你个人问题的新类型的构建块．图形表现上，一个模式化被表现为在双引号之内的名称(法国的引用形式是《》)，放置在另一个元件的名称之上．
Optionally the stereotyped element may be rendered by using a new icon associated with that stereotype.
