==Purpose and naming==
[[Wikt:mnemonic|Mnemonically]] ''''T'''emplate '''l'''ist e'''x'''panded'... after <tt>{{tlx|tl}}</tt> '''T'''emplate '''l'''ist' 

* This template takes another ''template-name'' and some associated [[w:pipe-trick|pipe-tricked]]  [http://meta.wikimedia.org/wiki/Parameter#Parameters (numbered) parameters] (or 'pass parameters'), and displays them as an 'example demonstration' of how the ''template-name'' template could be coded, literally. Its primary use is in instruction and documentation.

* '''''Specifics:''''' Up to five pass parameters (numbered or nowiki-keywords) for the specified template are displayed as 'placeholders', and over 5 parameters can be displayed using a coded vertical-bar (as in "<small>&amp;#124;</small>''...''"). A keyword parameter can be used, when tagged as a nowiki-keyword: <nowiki>"<nowiki>siz=10<\nowiki>"</nowiki> with each keyword parameter surrounded by <nowiki>"<nowiki>"</nowiki> tags; see ''[[#Examples|Examples]]'' at bottom. For more details, see the [[w:{{TALKPAGENAME}}|this talk]] page.

* '''''Exceptions:''''' If the intended template lists numerous/keyword parameters, then perhaps this template should really ''not'' be used, and just hardcode the usage with <code><nowiki>&lt;code&gt;&lt;nowiki&gt;</code>, for example: <code><nowiki>&lt;code&gt;&lt;nowiki&gt;{{Anytemplate|arg1=23|siz=250px|</nowiki><var>other parameters...</var><nowiki>}}&lt;/nowiki&gt;&lt;/code&gt;</nowiki></code>.  If a vertical display, with parameters on their own lines, is desired, this can also be laid out manually in this manner, or more rapidly done with <code><nowiki><pre>...</pre></nowiki></code>.

----

* If given no additional parameters except ''<code>&nbsp;'template&nbsp;name'&nbsp;(<nowiki>{{{1}}}</nowiki>), </code>''&nbsp;it presents the same as the similar {{tl|Tl}} [[W:macro|macro]] template -- a blue link nested in [[W:brackets|curly-braces]]-- the same as a user would apply the template without parameters, but with a noticably clearer font and spacing on most modern browsers. 

:* {{Tlx|Tl|Tl}} display compared to {{Tlx|Tlx|Tl}}: (Tl: {{Tl|Tlx}} versus Tlx: {{Tlx|Tl}}) 

* Comparatively, {{Tlx|Tl}} will not take or display additional parameters, and for minor technical reasons, may  preferred for mere listing and referencing in long pages involving a lot of template expansions[[W:WP:DPP|1]].

* Additionally, Tlx will take a 'named' parameter 'SISTER' to link interwiki to other sister projects such as one of these examples: '|SISTER=W:', 'Tlx|SISTER=M:', 'Tlx|SISTER=Q:', 'Tlx|SISTER=S:', allowing documentation or discourse about a template across interwiki boundaries. Small 'front end' Shell or convience templates {{Tlx|Tlxw}} and {{tlx|Tlxm}} are typing-aid templates available at Meta for automatic substitution in discussions about templates on Wikipedia or Meta.

----

;This usage also applies to interwiki capable template variations:
# {{Tl|Tlxc}} -- which links to templates on Wikimedia Commons (The Commons).
# {{Tl|Tlxm}} -- which links to templates on Meta
# {{Tl|Tlxw}} -- which links to templates on Wikipedia

----

==Documentation==

{&#123;[[Template:{{PAGENAME}}|{{PAGENAME}}]]&#125;}
is a generalization of {{Tlxw|Tl|x}}, {{Tlxw|Tlp|x|y}},
etcetera with arguably better readable
output. This depends on the browser, but too narrow
uses of "'''{'''", "'''|'''", "'''}'''" in conjunction
with links can be hard to read.

=== Usage ===

:<tt>{&#123;{{PAGENAME}}{{!}}template name&#125;}</tt>
:<tt>{&#123;{{PAGENAME}}{{!}}template name{{!}}param&#125;}</tt>
:<tt>{&#123;{{PAGENAME}}{{!}}template name{{!}}1{{!}}2{{!}}3&#125;}</tt>
:<tt>{&#123;{{PAGENAME}}{{!}}template name{{!}}1{{!}}2{{!}}3&amp;#124;more&#125;}</tt>
:<tt>{&#123;{{PAGENAME}}{{!}}template name{{!}}param&amp;#61;value&#125;}</tt>
''Up to three placeholders for parameters of the specified template''

=== Examples ===
{{#ifeq:{{SITENAME}}|Wikipedia|<!-- Skip message--->|
{{#ifeq:{{SITENAME}}|Meta|<!-- No note needed --->|<!-- Other Sisters Note: --->
;Note: On the source sister projects, en.wikipedia and Meta, '''X0, X1, X2,..., X9 are sandbox templates''' for experimentation on involved templates that need be in template space. An auto-cleansing software facility exists that might be used to duplicate the facility on other Sister projects.
