Some more convention questions

A colleague has raised the following questions, which I thought I would forward here for suggestions: 1. How should we mark up something like "www.example.com"? Note that we're here referring to a hostname, not a uri like "http://www.example.com" 2. Should we do anything to these (<application>, <code>, etc.): DNS DDNS SELinux ACL FQDN RPM BIND Most of these would fit under <ackronym>, but how would SELinux be marked up? Should BIND be treated as an ackronym or a service name? 3. During an installation, we have some SELinux choices: Disabled, Warn, Active. How should these be presented in CM? Would this work: <menuchoice> <guimenu>SELinux</guimenu> <guimenuitem>Disabled</guimenuitem> <guimenuitem>Warn</guimenuitem> <guimenuitem>Active</guimenuitem> </menuchoice> Or perhaps an itemizedlist? ...in other words, what's the proper markup for referring to a checkbox or radio button in a GUI form? 5. Should kernel options (e.g., enforcing=0) be <command> or <code>? 6. Which is more appropriate? <command>ls -l <filename>/etc/passwd</filename></command> or just <command>ls -l /etc/passwd</command> Finally, is there an established tag for use as a "catch-all" for things that we might want to be visually distinct, but that don't have docbook tags? SELinux contexts and dns hostnames come to mind. We're using <code>, but is there already a standard for this? On that note, is there anywhere that these conventions, like using <filename> for package names, which I saw in one of Karsten's examples, are codified? Or is it just something you have to ask a docs person? Thanks for all the help, --Brad --
