[osis-core] Isn't an <identifier type="OSIS"> element required within a <work> element that is used in osisRefWork or osisIDWork

[Todd Tillinghast]

Troy,

The tutorial is a beautiful thing and I think will really help those
trying to understand the basics!

My understanding is that in order to use the value in a "osisWork"
attribute in a <work> element as the value of "osisRefWork" or
"osisIDWork" in <osisText> that an <identifier> element with type="OSIS"
had to be present within the corresponding <work> element.

Is this something you don't agree with or was this just an oversight?

>From your tutorial:

In "The Header"
<header>
   <work osisWork="KJV">
       <title>King James Version of 1611</title>
       <language>en</language>                    
       <identifier type="OSIS">KJV.TutorEncoding</identifier>
       <refSystem>Bible.KJV</refSystem>
    </work>
    <work osisWork="defaultReferenceScheme">
        <refSystem>Bible.KJV</refSystem>
    </work>
</header>

Should include an <identifier> element in the 
<work osisWork="defaultReferenceSystem"> element.

As follows:

<header>
   <work osisWork="KJV">
       <title>King James Version of 1611</title>
       <language>en</language>                    
       <identifier type="OSIS">KJV.TutorEncoding</identifier>
       <refSystem>Bible.KJV</refSystem>
    </work>
    <work osisWork="defaultReferenceScheme">
       <refSystem>Bible.KJV</refSystem>
       <identifier type="OSIS">Bible.KJV</identifier>
    </work>
</header>
