从命令行或环境设置xerces功能

Question

我在命令行上使用Apache FOP将xsl：fo文件转换为pdf。

那些xsl：fo文件包含导致致命错误的<!DOCTYPE []>构造：

org.xml.sax.SAXParseException; systemId: file:/Y:/fo-files/Untitled.fo; lineNumber: 2; columnNumber: 10;
DOCTYPE is disallowed when the feature "http://apache.org/xml/features/disallow-doctype-decl" set to true.

必须将xerces "http://apache.org/xml/features/disallow-doctype-decl"功能设置为false。

如何从FOP命令行或环境（配置，属性或其他）设置该功能？
