[jira] [Comment Edited] (CAMEL-8287) Schematron component does not
work with includes in schematron
[ https://issues.apache.org/jira/browse/CAMEL-8287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15413612#comment-15413612 ]

------------------------------------------------------------
I'v been trying some things out and found that a possible way to fix this issue is to allow the user to configure the endpoint with an optional "Client" URIResolver.
{code:xml}
...
<to id="DD_METS-schematron-validation" uri="schematron:metadata/schematron/identifier_checks.sch?uriResolver=#customUriResolver"/>
...
{code}
This resolver would then be included in the components ClassPathURIResolver and be used as a fallback if the first resolve fail and the clientUriResolver is not null.
like this :
{code}

We use version 2.15.x of camel so i've based my experiments on this version of the component.

> </pattern>
> when I run against this schematron I get the following error:
> Recoverable error on line 472
