Dear Amanda, Using Schematron for validating these requirements is indeed a better approach because the validation is done on a separate execution thread and doesn't affect the layout.When a rule is broken, the visual indicator is a squiggly yellow line (or red, if you want to mark it as an error) which is pretty close to the way you are currently marking the element in the CSS rule (a yellow background). A CSS rule will give you more options on how to mark the error: colors, borders etc. Do you find the Schematron error marking (the yellow squiggly underline) enough or you would prefer to be able to change it to something else? Another option would be to use our Java based API and set a StylesFilter [1] and change the background color from there. In such an extension point you can directly navigate the author node model which is faster than executing an XPath. [1] https://www.oxygenxml.com/doc/versions/19.1/ug-editor/topics/dg-author-css-s...

Hi,
We’ve had a request from an author to make the formatting in the Author view indicate when the text of a certain element type does not match the text of something else found inside the same topic. I can do this via Oxygen CSS, but I am concerned that the processing slows down the opening of large documents. I’m not convinced that CSS is a good way to address the underlying requirement about helping authors detect when something does not have a textual match as expected (e.g., maybe Schematron or a build warning would be more appropriate).
Before I give up, though, I wanted to see if anyone had specific ideas or techniques I might have overlooked.
Here’s an example of variations I tried that work too slowly in large documents, just to give you the flavor.
/* true => 255*1 => white * false => 255*0 => yellow */ refentry[role="function"]literal{ background-color:oxy_xpath( "concat('rgb(255,255,', 255 * number(. = ancestor::refentry//term or .='') , ')')", evaluate,dynamic-once); }
Alternate:
refentry[role="function"]literal{ background-color:oxy_xpath( "if (exists(text()) and not(some $n in ancestor::refentry/refsect1[@role=('inputs','outputs')]//term satisfies string($n)=.)) then ('yellow') else ('')", evaluate,dynamic-once); }
Thanks,
Amanda
