In CSS, identifiers are generally case-insensitive. Therefore, in such
case, you need to use a string instead of an identifier.

Example (*BAD* will not work):

---
image {
  display: inline;
  content: image-viewport(attribute, srcFile,
                          data-type, anyURI);
}
---

Example (should work fine):

---
image {
  display: inline;
  content: image-viewport(attribute, "srcFile",
                          data-type, anyURI);
}
