Deployment Extensions online help: change the example

On the online help of Deployment Extension, here is the example given :
<extension target="pages#PAGES">
<page view-id="/nxstartup.xhtml"
action="#

{startupHelper.initDomainAndFindStartupPage('Default domain','user_dashboard')}

" />
</extension>
<extension target="web#SERVLET">
...
</extension>

Don't we recommend to put only one extension each time? If so, can we change the example to remove the second extension?
