// Is <null-ref> given ? Set 0 and return ok.
// 1a. Lookup the real address in memory, which should be aligned +++

// type mismatch gets by undetected, if the CDR stream fakes.
// So the type should be checked ... +++
// 2. Now at this point it must be a <value-tag> (error else).
// if (chunking) check that any last chunk ends with matching
// size. If not raise marshal exception.
// Increase the nesting level of valuetypes.
// 3. if (chunking) read and record the blocksize-tag.
// 4. Unmarshal type information and lookup factory.
// If no type information is given in the CDR encoding, as told
// from the <value-tag>, then use the repository id parameter
// (it _must_ be right).
