An element with a fixed value constraint carries its fixed character value and no element children, even under a mixed content type (cvc-elt.5.2.2.2.1). The fixed check compared only the concatenated text, so a mixed fixed element whose text matched the fixed value but which also contained child elements (ctZ013c/d) was accepted. elementFixedErrors now rejects a fixed element that has element children. An empty element (which takes the fixed value) and text equal to the fixed value remain valid. invalid-instances-accepted 37 to 34, no false positive (valid-instances-rejected and valid-schemas-rejected held at 0; a fixed element never validly carries element children), no other bucket moved.
