Eclipse plugin to remove validation from existing editor

I'm creating an Eclipse RCP application that handle a custom file format which is very similar to HTML so for the most part I can use the regular HTML editor that comes with Eclipse to take advantage of its features like syntax highlight and content assist, but this custom format includes some characters/tags that are invalid in HTML, for example <#= my text #> so when adding that to a file, like the following line:

<body><#= my text #></body>

the editor's validator will display this error:

Invalid character used in text string (<#= my text #>).

So I was wondering if it is possible to modify the behavior of an existing editor/validator to remove some specific validations and maybe add other ones.

Yes, although this sounds like something that would ideally start with a fork of the JSP Editor, from its parser all the way up...

If you defined a new content type using the org.eclipse.core.contenttype.contentTypes extension point (using your new file extension), and then supply a Validator to the source validation extension point, org.eclipse.wst.sse.ui.sourcevalidation, explicitly for your content type, the HTML validator should be skipped over in deference to the more specific one defined for your content type. https://github.com/eclipse/webtools.sourceediting/blob/0c532000ad09e53c9fb8ddfb1c3f1def983f57c0/core/bundles/org.eclipse.wst.sse.ui/src/org/eclipse/wst/sse/ui/internal/reconcile/DocumentRegionProcessor.java#L266 shows where it looks for validators specific to the content type and prefers those over any it would use defined in a base (less specific) content type.
