43 * IPP Delimiter Tags as described in RFC 2910 section 3.5.1.
44 * <p>
45 * Every delimiter tag value can occur in the protocol field
46 * begin-attribute-group-tag and indicates that the following
47 * attributes will be part of the named group.<br>
48 * The end-of-attributes-tag signals the end of the attributes
49 * section in the IPP request/response and therefore the beginning
50 * of the data section (if any).
