         <h1>ToNumber Applied to the String Type</h1>
         <p>ToNumber applied to Strings applies the following grammar to the input String interpreted as a sequence of UTF-16 encoded code points (<emu-xref href="#sec-ecmascript-language-types-string-type"></emu-xref>). If the grammar cannot interpret the String as an expansion of |StringNumericLiteral|, then the result of ToNumber is *NaN*.</p>
-        <emu-note>
-          <p>The terminal symbols of this grammar are all composed of characters in the Unicode Basic Multilingual Plane (BMP). Therefore, the result of ToNumber will be *NaN* if the string contains any <emu-xref href="#leading-surrogate"></emu-xref> or <emu-xref href="#trailing-surrogate"></emu-xref> code units, whether paired or unpaired.</p>
