 ## Assumptions
 
-- There is no mechanism to change the rendered text in the image resource. Otherwise, the rule might fail while [SC 1.4.5 Images of Text][sc1.4.5] and [SC 1.4.9 Images of Text (No Exception)][sc1.4.9] might be satisfied.
-- The specific presentation of the text rendered in the image resource can be achieved through formatted text. Otherwise, the rule might fail while [SC 1.4.5 Images of Text][sc1.4.5] and [SC 1.4.9 Images of Text (No Exception)][sc1.4.9] might be satisfied.

 - When used in HTML, the SVG `<text>` element is not considered to be an image of text. This is because like any other element in HTML, SVG `<text>` can be adjusted through custom style sheets. This does not apply for SVG text that is in a separate file, and displayed through, for example, the `img` element.
