Impossible to read ODT file previously saved by PHPWord as ODText

[ligoo]

Describe the Bug

Returning an empty array of element when trying to read an ODT file that has been saved by PHPWord previously.

Steps to Reproduce

<?php
require __DIR__ . '/vendor/autoload.php';

// Save
$phpWord = new \PhpOffice\PhpWord\PhpWord();
$section = $phpWord->addSection();
$section->addText('days');
$section->addText('monday');
$section->addText('tuesday');
$writer = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'ODText');
$writer->save('example.odt');

// Load
$reader = IOFactory::createReader('ODText');
$document = $reader->load('example.odt');

dd($document); // dd() laravel sugar but the idea is to inspect $document

Expected Behavior

Should return an array of PhpOffice\PhpWord\Element

Current Behavior

returns [] in $document->getSection(0)->elements

Leads

The library can properly read this (that is coming from libre office when creating a document saved as .odt file):

 <office:body>
  <office:text>
   <text:p text:style-name="P1">days</text:p>
   <text:p text:style-name="P1">monday</text:p>
   <text:p text:style-name="P1">tuesday</text:p>
  </office:text>
 </office:body>

but cannot read this (that is coming from the library when saving as .odt):

 <office:body>
  <office:text>
   <text:section text:style-name="Sect1" text:name="Section1">
    <text:p text:style-name="P1"/>
    <text:p text:style-name="Standard">days</text:p>
    <text:p text:style-name="Standard">monday</text:p>
    <text:p text:style-name="Standard">tuesday</text:p>
   </text:section>
  </office:text>
 </office:body>

Context

Please fill in your environment information:

• PHP Version: 8.2

FWIW, the document prepared by save appears to be valid; the problem does not lie with Writer/Odt. On the other hand, Reader/Odt has some gaps. At a minimum, Reader/ODText/Content has no support for text:section and text:span tags, and needs those.
