Hi community,

I'm currently woking in Sigil on a bilingual dictionary for Kindle. To define the Input and Output language I have to include a specialized <x-metadata> tag within the <metadata> tag in the content.opf file:

  <metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">
	...
	<x-metadata>
		<DictionaryInLanguage>pi</DictionaryInLanguage>
		<DictionaryOutLanguage>en</DictionaryOutLanguage>
		<DefaultLookupIndex>Pali</DefaultLookupIndex>
	</x-metadata>
	...
  </metadata>

When I save the file after including the <x-metadata> information in the *.opf file, Sigil removes it automatically.

Is there a way to keep non-standard metadata tags in the *.opf file?

Thanks in advance for your help 🙏
