Generally describing an element in terms of Salience gets the point across. For example, a component that should really stand out should be described and designed as "Highly Salient" while something that should be more subtle should have "Low Salience".
The decision about what elements should have high/low salience (or anywhere in between) should be a 1:1 mapping of salience : information importance. Critically important information should be the MOST salient element of a display, while other elements, like land marking, labels, copyright statements, etc. should have low salience because they're generally not a part of a user's workflow (even if they must be present in the design).
As stated above, the best question to ask here is why that element needs to stand out so much? That answer will help you determine to what degree it should be more salient that the rest of the element/content in your design.
