EE10: some dtd/xsd are missing:

Seeing this in logs:

WARNING 2024-03-25T20:50:08.512603Z The XML schema [XMLSchema.dtd] could not be found. This is very likely to break XML validation if XML validation is enabled.
WARNING 2024-03-25T20:50:08.513724Z The XML schema [datatypes.dtd] could not be found. This is very likely to break XML validation if XML validation is enabled.

These 3 warnings come from Apache Jasper.

• https://github.com/apache/tomcat/blob/10.1.20/java/org/apache/tomcat/util/descriptor/LocalStrings.properties#L16
• https://github.com/apache/tomcat/blob/10.1.20/java/org/apache/tomcat/util/descriptor/DigesterFactory.java#L180

This is because Jasper expects things for XML to appear in a specific directory location on the servlet-api jar, which it does for Tomcat, but not the official Servlet API Jar.

Those warnings just mention that XML validation will not work.
But the only code that uses that DigesterFactory is JSP.
So it would only impact XML for JSP, which I believe is limited to JSP custom taglib XML.

Note: even the latest Servlet API Jar for ee11 does not contain those 3 XML files.
