    <p>As indicated in <a href="#file-constraints">§ 7 General constraints</a>, an <a data-link-type="dfn" href="#avif-file" id="ref-for-avif-file③">AVIF file</a> is a compliant <a data-link-type="biblio" href="#biblio-miaf" title="Information technology -- Multimedia application format (MPEG-A) -- Part 22: Multi-Image Application Format (MiAF)">[MIAF]</a> file. As a consequence, some <a data-link-type="biblio" href="#biblio-isobmff" title="Information technology — Coding of audio-visual objects — Part 12: ISO base media file format">[ISOBMFF]</a> or <a data-link-type="biblio" href="#biblio-heif" title="Information technology — High efficiency coding and media delivery in heterogeneous environments — Part 12: Image File Format">[HEIF]</a> boxes are required, as indicated in the following table. The order of the boxes is indicative in the table. The specifications listed in the "Specification" 
 column may require a specific order for the box or for its children and shall be respected. For example, per <a data-link-type="biblio" href="#biblio-isobmff" title="Information technology — Coding of audio-visual objects — Part 12: ISO base media file format">[ISOBMFF]</a>, the <code><a data-link-type="dfn" href="https://www.iso.org/standard/68960.html" id="ref-for-something②⓪⓪">FileTypeBox</a></code> is required to appear first in an <a data-link-type="dfn" href="#avif-file" id="ref-for-avif-file④">AVIF file</a>.
