LPX-01050: [XPDY0050] Invalid dynamic type
Cause: It is a dynamic error if the dynamic type of the operand of a treat expression does not match the sequence type specified by the treat expression. This error might also be raised by a path expression beginning with "/" or "//" if the context node is not in a tree that is rooted at a document node. This is because a leading "/" or "//" in a path expression is an abbreviation for an initial step that includes the clause treat as document-node().
Action: None

LPX-01050：[XPDY0050]动态类型无效,
.原因：如果处理表达式的操作数的动态类型与对待表达式指定的序列类型不匹配，则是动态错误。如果上下文节点不在根文件节点的树中，也可能由以“/”或“//”开头的路径表达式引发此错误。这是因为路径表达式中的前导“/”或“//”是包含被视为document-node（）的子句的初始步骤的缩写。,
.行动：无,
