请记住，schemaLocation中的模式uri是在Schemas数据库而不是在网络中解决的。

说实话，我认为在MarkLogic中最简单的方法是根本不使用xsi：schemaLocation属性，而是在xqy中显式导入架构（使用import schema语句），以确保找到它正确。

顺便说一下，约书亚对Schematron的看法是正确的。 validate语句不执行Schematron验证。但是，MarkLogic确实提供了schematron支持，您可以手动应用它：

https://docs.marklogic.com/schematron

该模式大致如下。首先，将schematron和架构上载到架构数据库中。然后，您需要使用类似以下的命令来编译schematron文件：

xquery version "1.0-ml";

import module namespace schematron = "http://marklogic.com/xdmp/schematron" 
      at "/MarkLogic/schematron/schematron.xqy";

schematron:put("/schematron.sch")

此后，您将使用导入架构并进行验证以进行架构和schematron验证。像这样：

import schema namespace mods = "http://www.loc.gov/mods/v3" at "/mods-3-6.xsd";

import module namespace schematron = "http://marklogic.com/xdmp/schematron" 
      at "/MarkLogic/schematron/schematron.xqy";
