accept intralink when Embedding JSON-LD in HTML Documents

I am suggesting a small feature, for a future version of JSON-LD,  but it's
not clear whether it's a matter of  Syntax, API or  in some other document
that depends on the component specifications.

*ABSTRACT*: it is intended to make *content-reuse* as easy as Microdata or
RDFa+HTML make. The Embedding JSON-LD in HTML Documents
<https://www.w3.org/TR/json-ld11/#embedding-json-ld-in-html-documents> is a
good replacement for Microdata or RDFa+HTML, but to be complete need to
reuse *HTML content* *instead to duplicate it*. As in the Microdata
interpretation
<https://html.spec.whatwg.org/multipage/microdata.html#the-basic-syntax>,
the string to be translated, from cited (by *id*) HTHM element to plain
text must use a method defined by DOM standard
<https://en.wikipedia.org/wiki/Document_Object_Model>, the
*HTMLElement.innerText*
<https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/innerText>.

*EXAMPLE*: supposing an ID in the Example 164
<https://www.w3.org/TR/json-ld/#example-164-html-that-describes-a-book-using-microdata>
HTML fragment, something as

....
 <dt>Title</dt>
 <dd><cite id="tit01"
itemprop="http://purl.org/dc/elements/1.1/title">Just a
Geek</cite></dd>
....

the Example 165
<https://www.w3.org/TR/json-ld/#example-165-same-book-description-in-json-ld-avoiding-contexts>
JSON-LD fragment will be something as

[
  {
    "@id": "http://purl.oreilly.com/works/45U8QJGZSQKDH8N",
    "@type": "http://purl.org/vocab/frbr/core#Work",
    "http://purl.org/dc/elements/1.1/title": {"@id":"#tit01"},
    "http://purl.org/dc/elements/1.1/creator": "Wil Wheaton",
    "http://purl.org/vocab/frbr/core#realization": [...]
  }, ...
]

So, by the *innerText* rule, the *title *line will be equivalent to

   "http://purl.org/dc/elements/1.1/title": "Just a Geek"

Note: is a simple get-and-convert algorithm. In a Javascript parser the
string can be obtained by document.getElementById("tit01").innerText.

*RATIONALE*: reuse content, avoiding waste, errors or malicious changes...
And it is not only reuse, many legal applications (for Internet or digital
preservation scope), in Science and Justice, need document transparency and*
integrity guarantee*. Examples: JATS
<https://en.wikipedia.org/wiki/Journal_Article_Tag_Suite>,
SchemaOrg/Legislation <https://schema.org/Legislation>,
SchemaOrg/ScholarlyArticle <https://schema.org/ScholarlyArticle>, and other
official documents.
