Where can I find the XSDs of DOCX XML files?

Question

I\'ve created a docx file, unzipped it. Now I have:

• _rels (folder)
• docProps (folder)
• word (folder)
• [Content_Types].xml

Answer 1

[Content_Types].xml defines the MIME media types for the package parts in Open Packaging Conventions container-file technology that's a part of OOXML.

See the Standard ECMA-376 site, Part 2 of any edition, for the OPC XSDs, including the opc-contentTypes.xsd which you seek. It starts like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xs:schema xmlns="http://schemas.openxmlformats.org/package/2006/content-types"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  targetNamespace="http://schemas.openxmlformats.org/package/2006/content-types"
  elementFormDefault="qualified" attributeFormDefault="unqualified"
  blockDefault="#all">

  <xs:element name="Types" type="CT_Types"/>

Part 4 has references and XSDs for other parts of OOXML such as WordprocessingML, SpreadsheetML, PresentationML, DrawingML, Shared MLs and Custom XML Schema.
