- (* These hashtables are used internally by the parser to store
- * the conversion tables from 8 bit encodings to Unicode and vice versa.
- * It is normally not necessary to access these tables; the
- * Netconversion module does it already for you.
- *
- * Specification of the conversion tables:
- *
- * to_unicode: maps an 8 bit code to Unicode, i.e.
- * let m = Hashtbl.find `Enc_isoXXX to_unicode in
- * let unicode = m.(isocode)
- * - This may be (-1) to indicate that the code point is not defined.
- *
- * from_unicode: maps Unicode to an 8 bit code, i.e.
- * let m = Hashtbl.find `Enc_isoXXX from_unicode in
- * let l = m.(unicode land 255)
- * Now search in l the pair (unicode, isocode), and return isocode.
- *
- * Note: It is guaranteed that both arrays have always 256 elements.

-val lock : unit -> unit
- (* In multi-threaded applications: obtains a lock which is required to

-
-val unlock : unit -> unit
- (* In multi-threaded applications: releases the lock which is required to
- * Lazy.force the values found in to_unicode and from_unicode.
- * In single-threaded applications: a NO-OP

-(* The following comment was written when the conversion module belonged
- * to the PXP package (Polymorhic XML Parser).
- *)
-
-(* HOW TO ADD A NEW 8 BIT CODE:
- *
- * It is relatively simple to add a new 8 bit code to the system. This
- * means that the parser can read and write files with the new encoding;
- * this does not mean that the parser can represent the XML tree internally
- * by the new encoding.
- *
- * - Put a new unimap file into the "mappings" directory. The file format
- * is simple; please look at the already existing files.
- * The name of the file determines the internal name of the code:
- * If the file is called <name>.unimap, the code will be called
- * `Enc_<name>.
- *
- * - Extend the type "encoding" in pxp_types.mli and pxp_types.ml
- *
- * - Extend the two functions encoding_of_string and string_of_encoding
- * in pxp_types.ml
- *
- * - Recompile the parser
- *
- * Every encoding consumes at least 3kB of memory, but this may be much more
- * if the code points are dispersed on the Unicode code space.
- *
- * Perhaps the addition of new codes will become even simpler in future
- * versions of PXP; but it is currently more important to support
- * non-8-bit codes, too.
- * Every contribution of new codes to PXP is welcome!
