用schematron验证xml错误

[Mise_V]

同样的xml使用其他验证方式都行 用schematron就出现下面的错误 （都是书本的资源 没错误 ）

false Invalid schematron : Failed to compile stylesheet. 1 error detected.

以下为xml 和 sch代码
<?xml version="1.0" encoding="UTF-8"?>
<?schematron path="Library-1.sch"?>
<library>
<book id="ACMAS-20" publishedDate="1920" genre="Detective Fiction">

</book>
<book id="EGOSC-77" publishedDate="1977" genre="Science Fiction">

</book>
</library>
