Thread:Support/About MediaWiki:Apihelp-main-param-maxlag/ksh

Please provide hints as to how to translate: in this context which appears somewhat specific to MediaWiki.
 * replicated cluster
 * lag, maxlag

Can we localize $lag, $host - keeping the $ - since they are not variables and only appear as they are? Should they not consequentially be surrounded by &lt;var> tags, then?
