Yes, there may be a risk. The risk is that a schema doesn't incorporate business rules, nor does it document semantic meaning.

At best, it can only imply or hint, although that can sometimes be all that is needed. In the publishing field there are many vocabularies with element types such as

<title>
<main-title>
<subtitle>
<full-title>
<draft-title>
<called-title>
etc

Equally, there can just be <title> with attributes, and external documentation (think TEI) that explains in the finest possible detail EXACTLY how you construct the metadata from sources with multiple ways of expressing their title, including no title at all.

And then there's the best laid plans of mice and men...

The TEI for 'Moby-Dick' [1] from the 'Wright American Fiction' project
encodes a chapter opening like this:

   <div type="chapter">
      <head>CHAPTER I.</head>
      <head type="sub">LOOMINGS.</head>
      <p>Call me Ishmael...

Yes, 'CHAPTER I.' comes before and is larger than 'LOOMINGS' in the
printed book [2], but if the TEI documentation explains in the finest
possible detail how to deal with chapter numbers, someone didn't read
it.

Tony Graham.
