Correct notation for compound primary key

[JonasDoe]

I have a struct like this

type Relation struct {
	SourceID     mySQLTypes.ID  `gorm:"type:varbinary(16);primaryKey,priority:1;index:src_id_and_type,priority:1"`
	TargetID     mySQLTypes.ID  `gorm:"type:varbinary(16);primaryKey,priority:1;index:target_id_and_type,priority:1"`
	SourceType   string         `gorm:"primaryKey,priority:2;index;index:src_id_and_type,priority:2" sql:"type:varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci"`
	TargetType   string         `gorm:"primaryKey,priority:2;index;index:target_id_and_type,priority:2" sql:"type:varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci"`
}

This is faulty, b/c none of the primary key is set in the table, let alone their priorities.

Oh, found it out myself:
After short debugging through the source code, it the whole primaryKey entry is not parsed correctly:

So I figured I'ld might have to seperate these values with a semicolon, e.g. gorm:"type:varbinary(16);primaryKey;priority:1;index:src_id_and_type,priority:1". That seemed to work!
