Re: [web-annotation] Using xsd:date, too, in the model?

The RDFS definition of `dcterms:W3CDTF` shows it as a `rdfs:Datatype` 
- so it would indeed be valid to use it  `@type` on a literal (and 
wrong to use it as a property as COMBINE did)

```turtle
dcterms:W3CDTF
    dcterms:hasVersion 
<http://dublincore.org/usage/terms/history/#W3CDTF-003> ;
    dcterms:issued 
"2000-07-11"^^<http://www.w3.org/2001/XMLSchema#date> ;
    dcterms:modified 
"2008-01-14"^^<http://www.w3.org/2001/XMLSchema#date> ;
    a rdfs:Datatype ;
    rdfs:comment "The set of dates and times constructed according to 
the W3C Date and Time Formats Specification."@en ;
    rdfs:isDefinedBy <http://purl.org/dc/terms/> ;
    rdfs:label "W3C-DTF"@en ;
    rdfs:seeAlso <http://www.w3.org/TR/NOTE-datetime> .
```

aka it could be any of these:

```
   Year:
      YYYY (eg 1997)
   Year and month:
      YYYY-MM (eg 1997-07)
   Complete date:
      YYYY-MM-DD (eg 1997-07-16)
   Complete date plus hours and minutes:
      YYYY-MM-DDThh:mmTZD (eg 1997-07-16T19:20+01:00)
   Complete date plus hours, minutes and seconds:
      YYYY-MM-DDThh:mm:ssTZD (eg 1997-07-16T19:20:30+01:00)
   Complete date plus hours, minutes, seconds and a decimal fraction 
of a second
      YYYY-MM-DDThh:mm:ss.sTZD (eg 1997-07-16T19:20:30.45+01:00)
```

It would still be confusing without specifying deeper how to use 
`dcterms:W3CDTF` as the DC Terms page is not very helpful.
