Bản mẫu:Catalog lookup link/doc

This generic link template is used by other more specific templates to create short links to ID-based entries in external databases or catalogs, however, it can also be used to link to internal articles. The purpose of this template is to ensure a consistent appearance and easier maintenance of links to external databases/catalogs.
The template supports up to 9 unnamed parameters for the ID entries as well as a number of optional named parameters to adjust the link format to the target database and to modify the display format to make it suitable for as many catalog links as possible.
While additional format options might be provided in the future, the default output should always remain a short, but clear and unobtrusive single-line format suitable for inclusion as argument of the id parameter of the various chú thích templates. Typically, the template is not used directly, but indirectly called through other more specific templates (like those listed below under See also).

**Các tham số**
1, 2, 3, 4, 5, 6, 7, 8, 9: Optional unnamed parameters for 0 to 9 items to be listed. Whitespace is trimmed off both ends and the strings are urlencoded as if they were query strings.
*article-link: Optional Wikipedia article name to link to.
*article-name: Optional alternative text to be displayed for article-link link in front of catalog link. If not specified, article-link is used for display as well. If both parameters are not specified, the prefix is omitted completely.
*article-postfix: Optional symbol to be displayed after article name or link (f.e. ":"; omitted, if not defined).
*link-prefix: Optional prefix portion of url to external catalog item(s).
*link-postfix: Optional postfix portion of url to external catalog item(s).
*item-prefix: Optional text displayed in front of each external link (omitted, if not defined)
*item-postfix: Optional text displayed immediately after each external link (omitted, if not defined)
*list-separator: Optional alternative separator displayed between list items (default: ", ", if not specified). Whitespace must be encoded.
*list-leadout: Optional alternative leadout text displayed between the last two list items (f.e. "and", "or", "as well as", etc., default is the list-separator or ", ".)
*leadout-postfix: Optional alternative postfix text of the leadout (see list-leadout) displayed between the last two list items. This gets added in front of the last list item instead of the default whitespace which is added without this parameter. This may be necessary if list-separator is used not only to define the list separator but also parts of the item prefix (except for the first one). (At present, this is used only to cope with format oddities of the MR template.)
