what 's "store xsl,html into Tamino to for the representati

I got a demo,that’s may be according as the thought that “store xsl,html into Tamino for the representation of xml”,because I saw more doctype in one collection,and they are xsl,html
.that demo meant to retrieve a jpg file,to store NONxml,there must define a collection only have a doctype and a node ,I did it,and Store jpg into Tamino,and I saw it.In another doctype ,I define a attribute name for file to link the jpg name,I don’t know how to do next!
anyone who give me the information about this will be popular!
best regards!
