2.1.384 Part 1 Section, attachedTemplate (Attached Document Template)

a.   The standard states that the id attribute specifies the relationship that shall have the type required by the parent element, yet a relationship type for the attachedTemplate element is not listed.

Word requires http://schemas.openxmlformats.org/officeDocument/2006/relationships/attachedTemplate as the relationship type for the attachedTemplate element, as specified in "[ISO/IEC-29500-1] §11.4".

b.   The standard states that this element's val attribute shall contain the file path of the associated document template.

Word does not support a val attribute for the attachedTemplate element. The file path for the associated document template is determined by evaluating the relationship ID on this element.
