Hi John,
OK, so my adding xlink:type="simple" does not break anything. Good.
But
3.2 Markup Conformance
An XML element conforms to XLink if:
1.
it has a |type| attribute from the XLink namespace whose value
is one of "simple", "extended", "locator", "arc", "resource",
"title", or "none", and
2.
it adheres to the conformance constraints imposed by the chosen
XLink element type, as prescribed in this specification.
So I am asking, politely I hope, to make xlink:type required, so that we
conform to the xlink spec.
For starters, could all the thredds files that you generate have that
attribute?

we do already allow the "show" and "type" attribute on an Xlink, see:

XLink Attribute Group
<xsd:attributeGroup name="XLink">
<xsd:attribute ref="xlink:href" />
<xsd:attribute ref="xlink:title" />
<xsd:attribute ref="xlink:show"/>
<xsd:attribute ref="xlink:type" />
</xsd:attributeGroup>
These are attributes from the XLink specification
<http://www.w3.org/TR/xlink/> that are used to point to another web
resource. The /xlink:href/ attribute is used for the URL of the
resource itself. The /xlink:title/ attribute is what should be
displayed to the user. These are the only two attributes currently
used in the THREDDS software.You can also add the /xlink:type /or/
xlink:show /attributes/. /
