A few questions on XML and oracle:
1. What are entiry referenes in XML? Are they only required for special characters?
2. Are those entities "&#nnnn" same as ASCII representation?
3. Does valid XML require to print special symbols/diacritics in numeric entity referenes?
4. How can i get the special characters from oracle database to print in those numeric entities so that XML parsers can read them since they can't seem to read the special character.
