You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: builder.go
    path of file: ./repos/permify/pkg/schema
    
    the code of the file until where you have to start completion: package schema

import (
	"strings"

	"github.com/google/cel-go/cel"

	"github.com/Permify/permify/pkg/dsl/utils"
	base "github.com/Permify/permify/pkg/pb/base/v1"
)

// Schema is a function that returns a pointer to a SchemaDefinition structure. It takes a variable number of pointers to
// EntityDefinition structures as input arguments, which are adde
    
func Reference(name string) *base.RelationReference {
	// Split the name parameter into a type and relation if it contains a "#"
	s := strings.Split(name, "#")
	if len(s) == 1 {
		// If no relation is specified in the name, return a RelationReference with an empty relation field
		return &base.RelationReference{
			Type:     s[0],
			Relation: "",
		}
	}
	// If a relation is specified in the name, return a RelationReference with both type and relation fields populated
	return &base.RelationReference{
		Type:     s[0],
		Relation: s[1],
	}
}
