Just like embed video have Parser Tag for Templates like this

{{#evt: service=youtube |id=https://www.youtube.com/watch?v=pSsYTj9kCHE |alignment=right }}

so I could setup a template like this
Template:embedvideo as

{{#evt: service=youtube |id=https://www.youtube.com/watch?v={{{1}}} |alignment=right }}

then I could call like this

{{Template:embedvideo|pSsYTj9kCHE}}

if rss could have the Parser Tag for Templates

maybe we have one template

Template:cnn_rss as

{{#rss: max=10 |id=http://rss.cnn.com/rss/{{{1}}} |..... }}

so we would call like

{{Template:cnn_rss|edition_world.rss}}

or

{{Template:cnn_rss|edition_asia.rss}}

could we?
