Problem Statement:
As XML uses some characters for tags and attributes into its syntax. So, it’s not possible to directly use those characters inside XML tags or attribute values.
Solution:
To use the special characters (such as Comma and Hyphen etc) inside XML tags one should must use the numeric reference instead of that character. The numeric character reference must be of UTF-8 because the supported encoding for XML files is defined in the prolog as encoding="UTF-8" and should not be changed.
Format:
The numeric character reference uses the format:
&#nn; for decimal form
&#xhh; for hexadecimal form
&#nn; for decimal form
&#xhh; for hexadecimal form
