HL_CompoundTypeDescription

This type is a list of HL_CompoundTypeAttributes. The reason why it's called ``Description'' is that it acts more like meta data than actual data, since it's just a collection of other nodes which may contain data, and is therefore more of a description than anything else. It is structured like this:

typedef struct {
   char typename[256];          /* the list's name */
   unsigned long objno[2];      /* markers used to tag nodes in the list */
   size_t size;                 /* size of this data type */
   int nAttrs;                  /* the number of attributes in the list */
   int nAllocAttrs;             /* the number of allocated attributes */
   HL_CompoundTypeAttribute** attrs; /* the attributes themselves */
} HL_CompoundTypeDescription;
