[英]Create an untyped literal from a String value with a specified language.
[中]使用指定语言从字符串值创建非类型化文字。

代码示例

/**
 * <p>Remove the statement that the given string is a label for
 * this resource.  If this statement
 * is not true of the current model, nothing happens.</p>
 * @param label A label string to be removed
 * @param lang A lang tag
 */

/**
 * <p>Answer true if this resource has the given comment.</p>
 * @param comment The comment to test for
 * @param lang The optional language tag, or null for don't care.
