| There are statements elsewhere about the semantics:
[Definition: XML documents should begin with an XML declaration which specifies the version of XML being used.]
And this provides a context within which readers are likely to understand what "version number" means. Without this context, it could easily be the version of the vocabulary, or the version of the instance document.

It is true that the quoted sentence presupposes a basic
understanding on the part of the reader of what is meant by
"version number". But without this basic understanding the whole
specification would have no meaning at all. After all, the sentence is normative. For what reason does the
XML specification make statements about permissible values of the
attribute if it is completely unclear what its semantic should be?

Kay:
Section 2.8 Prolog and Document Type
Declaration Production Rule 26 VersionNum together with
the following note, which explains the semantic of
VersionNum as a decimal Number:
"Even though the VersionNum production matches
any version number of the form '1.x', XML 1.0 documents
SHOULD NOT specify a version number other than '1.0'." Greetings, Frank
That doesn't say anything about the semantics of the version
number, it just gives some constraints on its value. It doesn't
say what information it conveys: for all this sentence says,
VersionNum tells you the number of phone calls made on an
average day by the document author.
