<div class="plainlinks template-documentation"><div style="padding-bottom:3px; border-bottom:1px solid #aaa; margin-bottom:1ex; "><span class="editsection">[[[{{{1|{{SUBJECTPAGENAME}}/doc}}}|view]]] [[{{fullurl:{{{1|{{SUBJECTPAGENAMEE}}/doc}}}|action=edit{{#ifexist: {{{1|{{SUBJECTSPACE}}:{{SUBJECTPAGENAMEE}}/doc}}} ||&preload=Template:Documentation/preload}}}} edit]]</span> <span style="font-size: 150%">Documentation</span></div>
<div id="template_doc_page_transcluded" class="dablink plainlinks">This [[Wikipedia:Template documentation|documentation]] is [[Wikipedia:Transclusion|transcluded]] from [[{{{1|{{FULLPAGENAME}}/doc}}}]] ''([{{fullurl:{{{1|{{SUBJECTPAGENAMEE}}/doc}}}|action=edit{{#ifexist: {{{1|{{SUBJECTSPACE}}:{{SUBJECTPAGENAMEE}}/doc}}} ||&preload=Template:Documentation/preload}}}} edit] • [{{fullurl:{{{1|{{SUBJECTPAGENAME}}/doc}}}|action=history}} history])''. {{#ifexist: {{#rel2abs: /sandbox }}| {{#ifexist: {{#rel2abs: /testcases}} |<br> This template has a [[/sandbox|sandbox]] ''([{{fullurl:{{FULLPAGENAME}}/sandbox|action=edit}} edit])'' and [[/testcases|testcases]] for editors to experiment.}}<!-- else don't show when just 1 of /sandbox or /testcases exists --> }} </div>{{{{{1|{{SUBJECTPAGENAME}}/doc}}}}}<br style="clear:both;" /></div>
