Thanking you.
The answer to your question is in subclause 16.8: ------------------------------------------------ 16.8 If any part of the "XMLValue" production results in an XML start-tag immediately followed by an XML end-tag, possible separated by white-space inserted as permitted by 11.1.4 (for example, <field1></field1>), these two XML tags, and any intervening white-space, can be replaced by a single XML empty-element tag (<field1/>). ------------------------------------------------ This means that any occurrence of <xyz></xyz> can be written as <xyz/>.
