[osis-core] Global attribute: new for osis_0106!

[Patrick Durusau]

Guys,

For OSIS_0106, new global attribute:

<xs:attributeGroup name = "globalAttributes">
		<xs:attribute name = "ID" type = "xs:ID" use = "optional" />
		<xs:attribute name = "IDREF" type = "xs:IDREF" use = "optional" />
		<xs:attribute name = "IDREFS" type = "xs:IDREFS" use = "optional" />
		<xs:attribute name = "lang" type = "languageType" use = "optional" />
		<xs:attribute name = "reference" type = "ReferenceType" use = "optional" />
		<xs:attribute name = "referenceEnd" type = "ReferenceType" use = "optional" />
		<xs:attribute name = "type" type = "xs:string" use = "optional" />
</xs:attributeGroup>

Note that globalAttributes replaces the globalAttributesWithType and 
globalAttributesWithoutType, and milestone attributes. Also allows 
removal of start/end/Element stuff from attributes.

Here's the skinny:

ID: who-am-i, just a string, must be unique. Can overload as verse 
reference (for verse milestone) but probably should not try that for 
other elements.

IDREF: where I point, mainly for closing milestones

IDREFS: space separate string of IDs, allows attachment of notes, etc. 
(does mean that people have to use valid IDs for the notes to have 
something to attach to, but that would be the case anyway)

lang: languages of the element

reference: where-am-i-pointing, note default is validation by 
compScriptureRefType.xsd or x-

referenceEnd: where-do-i-stop-pointing, same as above

With reference and referenceEnd, any element can point outside the 
document to another, but validation at this point is only for scripture. 
As we define other reference schemes, should be unions of x- and the 
scheme so that older materials validate.

type: just a string, whatever classification makes sense, probably 
should require some sort of documentation on it.

Rocking and working!

Patrick
