Quelltext der Seite Vorlage:Block bug documentation

<noinclude>{{notice|Ignore any errors showing below; they do not appear when this snippet is transcluded (nor does this message box). This doc snippet's output only works when it's transcluded into the context of a specific template, e.g. at [[Template:Block indent/doc]]}}

</noinclude>If the block-formatted content begins with a list (or any other wikimarkup that is dependent upon a specific markup character being at the beginning of a line) then due to a bug in [[MediaWiki]], a {{xtag|nowiki|s}} must exist before the list (or whatever) starts. Compare:
{| class="wikitable"
|-
! &nbsp;
! scope="col" | code
! scope="col" | result
|-
! scope="row" | FAIL
|
  {{{{BASEPAGENAME}}<nowiki>|</nowiki>{{{1|1}}}<nowiki>=
 *Firstly, ...
 *Secondly, ...
 *Thirdly, ...
 }}</nowiki>
| <includeonly>{{{{BASEPAGENAME}}|{{{1|1}}}=
*Firstly, ...
*Secondly, ...
*Thirdly, ...
}}</includeonly><noinclude>{{error|This output only works when this doc snippet is transcluded.}}</noinclude>
|-
! scope="row" | Works as intended

  {{{{BASEPAGENAME}}<nowiki>|</nowiki>{{{1|1}}}<nowiki>=</nowiki>'''&lt;nowiki /&gt;'''<nowiki>

To embed a table in block markup like this, the block template's content parameter must be named or numbered and include the self-closing noinclude – as in <code><nowiki>|1=&lt;nowiki /&gt;</nowiki></code> – then every <code><nowiki>|</nowiki></code> character in the table markup must be escaped with {{tlx|!}}. An alternative is to use explicit HTML {{code|lang=html|code=<table>}}, {{code|lang=html|code=<tr>}}, {{code|lang=html|code=<th>}}, and {{code|lang=html|code=<td>}} markup.<noinclude>
{{Documentation|content=This is transcluded documentation, which can be transcluded in the /doc pages of various templates like {{tlx|Block indent}} and {{tlx|Quote}}, e.g. under a "Technical issue with block templates" heading or the like.  Right now it takes no parameter other than {{para|1|{{var|foo}}}}, to change the <code><nowiki>{{{1}}}</nowiki></code> to something else, thus changing the display (and operation) to use something other than {{para|1}} in the shown template operations.
