DBMS_METADATA.GET_DDL- how does it format output

Question

I call "DBMS_METADATA.GET_DDL" to get package body source code, see example call below.
Can i be always sure that it will always:
1. Return schema name before package name as for example this: "MYSCHEMA"."COLLECTSTATS". Or may it return sometimes without schema/owner-name the package name as " CREATE OR REPLACE PACKAGE BODY "COLLECTSTATS" IS"
2. Will it always be in capital letters the "owner.packagename" part?
3. wil lthere always be Double quotes surrounding package name and owner name as "MYSCHEMA"."COLLECTSTATS"?
select DBMS_METADATA.GET_DDL('PACKAGE_BODY','COLLECTSTATS','MYSCHEMA') from DUAL;
Result:
CREATE OR REPLACE PACKAGE BODY "MYSCHEMA"."COLLECTSTATS" IS
    PROCEDURE save_log(p_logrec IN LiveStatsLog%ROWTYPE) IS

Can i be always sure that it will always:
1. Return schema name before package name as for example this: "MYSCHEMA"."COLLECTSTATS". Or may it return sometimes without schema/owner-name the package name as " CREATE OR REPLACE PACKAGE BODY "COLLECTSTATS" IS"This is controlable through a parameter
2. Will it always be in capital letters the "owner.packagename" part?If you have created object names with double quotes when you defined it like:
Create package "p"then no, it will keep the case as it appears in the data dixtionary. If you never use double quotes when creating objects, then ot will always be upper case.
3. wil lthere always be Double quotes surrounding package name and owner name as "MYSCHEMA"."COLLECTSTATS"?Yes, this is done so that case can be preserved if neccessary.
