I've seen that discussion, but had problems with mail server and couldn't
join to it.

My proposal is a little different. While input modules provide a way to
_get_ variable values from different sources (sitemap, request, etc.), my
need is to _set_ global parameters for the sitemap to avoid things like
@skin@ in matcher patterns, etc. Of course these params can be used as
"sitemap:param-name" everywhere when needed. The above example would look
like:

<map:transform src="skins/{sitemap:skin}/xslt/html/{type}.xsl">.

Behavior can be the same as for the XSLT params: if a value is specified
externally (from command line or request params) then it's used, otherwise
the default value is used that is specified in declaration of the parameter:

<map:parameter name="skin" value="forrest-skin" />
