/** Descriptor for XER encoding/decoding during runtime.
 *
 * This structure contains XER enc/dec information for the runtime.
 *
 * There is an instance of this struct for most TTCN3/ASN1 types.
 * Because TITAN generates type aliases (typedefs) when one type references
 * another (e.g. "type integer i1" results in "typedef INTEGER i1"),
 * this struct holds information to distinguish them during encoding.
 *
 * Only those encoding instructions need to be recorded which can apply to
 * scalar types (e.g. BOOLEAN, REAL, etc., usually implemented by classes in core/)
 * because the same code needs to handle all varieties.
 *
 *  - ANY-ELEMENT : UFT8String
 *  - BASE64      : OCTET STRING, open type, restricted character string
 *  - DECIMAL     : REAL
 *  - NAME        : anything (this is already present as \c name)
 *  - NAMESPACE   : hmm
 *  - TEXT        : INTEGER, enum
 *  - USE-NUMBER  : enum
 *  - WHITESPACE  : restricted character string
 *
 * ANY-ATTRIBUTE, EMBED-VALUES, LIST, USE-TYPE, USE-UNION apply to sequence/choice types;
 * their effect will be resolved by the compiler.
 *
 * Instances of this type are written by the compiler into the generated code,
 * one for each type. For a TTCN3 type foo_bar, there will be a class
 * foo__bar and a XERdescriptor_t instance named foo__bar_xer_.
 *
 * Each built-in type has a descriptor (e.g. INTEGER_xer_) in the runtime.
 *
 * The \a name field contains the closing tag including a newline, e.g.
 * \c "</INTEGER>\n". This allows for a more efficient output of the tags,
 * minimizing the number of one-character inserts into the buffer.
 *
 * The start tag is written as an 'open angle bracket' character,
 * followed by the \a name field without its first two characters (\c "</" ).
 *
 * In case of the canonical encoding (\c CXER ) there is no indenting,
 * so the final newline is omitted by reducing the length by one.
 *
 * Example:
 * @code
 * int Foo::XER_encode(const XERdescriptor_t& p_td,
 *                     TTCN_Buffer& p_buf, unsigned int flavor, int indent, embed_values_enc_struct_t*) const {
 *   int canon = is_canonical(flavor);
 *   if (!canon) do_indent(p_buf, indent);
 *   // output the start tag
 *   p_buf.put_c('<');
 *   p_buf.put_s((size_t)p_td.namelen-2-canon, (const unsigned char*)p_td.name+2);
 *   // this is not right if Foo has attributes :(
 *   // we'll need to reduce namelen further (or just get rid of this hackery altogether)
 *
 *   // output actual content
 *   p_buf.put_.....
 *
 *   // output the closing tag
 *   if (!canon) do_indent(p_buf, indent);
 *   p_buf.put_s((size_t)p_td.namelen-canon, (const unsigned char*)p_td.name);
 * }
 * @endcode
 *
 * Empty element tag:
 *
 * @code
 * int Foo::XER_encode(const XERdescriptor_t& p_td,
 *                     TTCN_Buffer& p_buf, unsigned int flavor, int indent, embed_values_enc_struct_t*) const {
 *   int canon = is_canonical(flavor);
 *   if (!canon) do_indent(p_buf, indent);
 *   // output an empty element tag
 *   p_buf.put_c('<');
 *   p_buf.put_s((size_t)p_td.namelen-4, (const unsigned char*)p_td.name+2);
 *   p_buf.put_s(3 - canon, (const unsigned char*)"/>\n");
 * }
 * @endcode
 *
 * @note We don't generate the XML prolog. This is required for Canonical XER
 * (X.693 9.1.1) and permitted for Basic-XER (8.2.1).
 *
 * @note X.693 amd1 (EXER) 10.3.5 states: If an "ExtendedXMLValue" is empty,
 * and its associated tags have not been removed by the use of an UNTAGGED
 * encoding instruction, then the associated preceding and following tags
 * <b>can (as an encoder's option)</b> be replaced with
 * an XML empty-element tag (see ITU-T Rec. X.680 | ISO/IEC 8824-1, 16.8).
 * This is called the associated empty-element tag.
 *
 * @note X.693 (XER) 9.1.4 states: (for Canonical XER)
 * If the XML value notation permits the use of an XML empty-element tag
 * (see ITU-T Rec. X.680 |ISO/IEC 8824-1, 15.5 and 16.8),
 * then this empty-element tag @b shall be used.
 *
 * @note After editing XERdescriptor_t, make sure to change XER_STRUCT2 here
 * and generate_code_xerdescriptor() in Type.cc.
