How to initialize a struct in accordance with C programming language standards

Question

I want to initialize a struct element, split in declaration and initialization. This is what I have:

typedef struct MY_TYPE {
  bool flag;
  short int value;

I've been looking for a nice way to initialize my struct, and I've got to using the below (C99). This lets me initialize either a single structure or an array of structures in the same way as plain types.

typedef struct {
    char *str;
    size_t len;
    jsmntok_t *tok;
    int tsz;
} jsmn_ts;

#define jsmn_ts_default (jsmn_ts){NULL, 0, NULL, 0}

This can be used in the code as:

jsmn_ts mydata = jsmn_ts_default; /* initialization of a single struct */

jsmn_ts myarray[10] = {jsmn_ts_default, jsmn_ts_default}; /* initialization of
                                                    first 2 structs in the array */
