How about change the PcdValue as below since we also support the integer= value. ::=3D {} {} {} {} ::=3D {} {} ::=3D {(0-9)} {(1-9)(0-9)+} 2. How about change HexNumber to support the upper case "0X" ? ::=3D {"0x"} {"0X"} (a-fA-F0-9){1,16} 3. No definition. How about add this one ? ::=3D {"0x"} {"0X"} (a-fA-F0-9){1,2} 4. A typo error (it is INF, not INC) in sentence " command-line take preced= ence over PCD provided in DSC, FDF, INC, and DEC files".
