Body: <p>According to the epub spec a page number can be defined as:</p>
  
  <pre><code>&lt;p&gt;
     …
     &lt;span epub:type="pagebreak" id="page23"&gt;23&lt;/span&gt;
     …
  &lt;/p&gt;
  </code></pre>
  
  <p>And in the page-list:</p>
  
  <pre><code>&lt;nav epub:type="page-list"&gt;
    &lt;ol&gt;
      …
      &lt;li&gt;&lt;a href="georgia.xhtml#page752"&gt;752&lt;/a&gt;&lt;/li&gt;
      …
    &lt;/ol&gt;
  &lt;/nav&gt;
  </code></pre>
  
  <p>Does the value of the page number need to be a integer value? In otherwords, will the following be valid:</p>
  
  <pre><code>&lt;p&gt;
     …
     &lt;span epub:type="pagebreak" id="pagei"&gt;i&lt;/span&gt;
     …
  &lt;/p&gt;
  </code></pre>
  
  <p>Will this cause issues on any of the popular readers?</p>

Comments.Text: Amazingly, neither the latest Kindle Formatting Guide or ibooks asset guide mention any directions here. So I think you can assume that support is either epxerimental or nonexistent.

  (Asked by: username_0 on 2015-12-10)
  
  According to the epub spec a page number can be defined as:
  
  ```
  <p>
     …
     <span epub:type="pagebreak" id="page23">23</span>
     …
  </p>
  
  ```
  
  And in the page-list:
  
  ```
  <nav epub:type="page-list">
    <ol>
      …
      <li><a href="georgia.xhtml#page752">752</a></li>
      …
    </ol>
  </nav>
  
  ```
  
  Does the value of the page number need to be a integer value? In otherwords, will the following be valid:
  
  ```
  <p>
     …
     <span epub:type="pagebreak" id="pagei">i</span>
     …
  </p>
  
  ```
  
  Will this cause issues on any of the popular readers?

  Support for actual page numbers is practically non-existent on almost all e-readers. You've tagged this epub3—I'll point out that epub3 support is *also* practically non-existent...
  
  I don't think using non-integer values is going to cause issues on many readers, because I doubt many of them will care. I also don't think many of them will break on the page, unless you have explicit css to force a page break.
