 \section{Version Specifications}
 \label{sec:version-spec}
 The package manager must not impose fixed limits upon the number of version components. Package
-managers should indicate or reject any version that is invalid according to these rules.
+managers shall at least accept integer components up to 18 digits; however, it is recommended that
+they accept an arbitrary length. Package managers should indicate or reject any version that is
+invalid according to the rules below.
 
 A version starts with the number part, which is in the form \t{[0-9]+(\textbackslash.[0-9]+)*}
 (a positive integer, followed by zero or more dot-prefixed positive integers).
