Michele,
Martin wrote "xsl:key", but for whatever reason his fingers seem to have
typed "xsl:name". Try what he meant to say and it should work.
If you aren't familiar with keys and how powerful and useful they are,
now is a good moment to learn. One of their several uses is in getting
around scaling problems when grouping (or doing any handling of unique
values) in XSLT 1.0.
Also ... your diagnosis is not *quite* correct yet:
<xsl:variable name="uniqueTypes"
select="ead/archdesc/dsc/descendant::*/container[not(@type=following::
*/container/@type)]/@type" />
With the root node as context, this is selecting all container elements
in descendants of /ead/archdesc/dsc whose type is not the same as that
of a container *child* of a following element.
So, while following siblings are indeed found on the following:: axis,
this in fact is checking elements against nieces (and/or nephews) or
cousins (at various removes), but not against siblings.
Cheers,
Wendell

Do I put this at the top, where it is now? I tried it there and it tells me
Element:<xsl:name> must not appear directly within xsl:stylesheet

Pretty sure they're using 1.0 but I can check.
Define a key
<xsl:name name="uniqueTypesKey"
match="ead/archdesc/dsc/descendant::*/container"
use="@type" />
and then the variable as
<xsl:variable name="uniqueTypes"
select="ead/archdesc/dsc/descendant::*/container[generate-id() =
generate-id(key('uniqueTypesKey', @type)[1])]"/>
