A suggestion for OpenSearch

Instead of having a separate OpenSearch description file and then the results in Atom, why not put the OpenSearch description in the Atom header, eg instead of:

<OpenSearchDescription>
	<ShortName>HubLog</ShortName>
	<Description>weblog</Description>
	<Contact>alf@hubmed.org</Contact>
	<Url type="application/atom+xml" template="http://hublog.hubmed.org/cgi-bin/mt/mt-search.cgi?IncludeBlogs=2&search={searchTerms}&Template=opensearch"/>
	<Url type="text/html" template="http://hublog.hubmed.org/cgi-bin/mt/mt-search.cgi?IncludeBlogs=2&search={searchTerms}"/>
	<LongName>HubLog</LongName>
	<Image height="16" width="16" type="image/vnd.microsoft.icon">http://hublog.hubmed.org/favicon.ico</Image>
</OpenSearchDescription>

have

<feed xmlns="http://www.w3.org/2005/Atom" xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/">
    <title>HubLog</title>
    <id>tag:hublog.hubmed.org,2006://2</id>
    <subtitle>weblog</subtitle>
    <link rel="alternate" type="text/html" href="http://hublog.hubmed.org/" />
    <link rel="self" type="application/atom+xml" href="http://hublog.hubmed.org/index.atom"/>
    <opensearch:link rel="search" type="application/atom+xml" href="http://hublog.hubmed.org/cgi-bin/mt/mt-search.cgi?IncludeBlogs=2&search={searchTerms}&Template=opensearch"/>
    <opensearch:link rel="search" type="text/html" href="http://hublog.hubmed.org/cgi-bin/mt/mt-search.cgi?IncludeBlogs=2&search={searchTerms}"/>
    <icon href="http://hublog.hubmed.org/favicon.ico"/>
