</span></span></span><![endif]><span style="color:#1F497D">There syntax should be versioned , and the version should be indicated in the catalogue somewhere – whatever we agree on, there is bound to be need to change in the future, and changes will be much
easier to manage if we have the version in the catalogue. There could be independent syntax versions for the top level catalogue and the “publication unit” catalogue. The cleanest way to do this would be with an xsd document referenced in the schemaLocation
attribute. We could set this up initially with a “permissive” xsd schema imposing necessary constraints, but not all the required constraints.<o:p></o:p></span></p>

</span></span></span><![endif]><span style="color:#1F497D">The decision to stick to a 2-level hierarchy of THREDDS documents (a top-level catalogue with a list of “catalogRef”s and a sub-catalogue for each publication unit) is certainly right for now, but may
be too restrictive in the medium term. The specification of “catalogRef” means that very little information is in the top level, and at the next level you have to fetch everything. Having an 3<sup>rd</sup> level – e.g. for each simulation – would allow more
flexibility in recording changes and pointing to documentation. <o:p></o:p></span></p>
