---++ Notes on Implementations and Validaters

The StandardsRegExt page includes three compliant sample VOResource instances that use the StandardsRegExt extension. Instances can be validated with an XML Schema validater such as the one provided with [[http://trac.us-vo.org/project/nvo/wiki/Junx][Junx]] (which is based on Xerxes).

---+++ Comments from IVOA.MarkTaylor

This document looks mostly good, and the !StandardKeyEnumeration element in particular is a useful tool.  I have a few comments and corrections:
   1. The schema presented in Appendix A appears to be badly-formed XML.  If I attempt to parse it, it chokes on ampersands in a couple of the regular expressions.  They need to be escaped ("&amp;" -> "&amp;amp;").  The presence of this fundamental error suggests that no testing (e.g. attempted validation of actual !StandardsRegExt instances) has been done on this version of the schema -- is that the case?
      * it is just a transcription error in copying the schema text to a html representation - the schema itself at http://www.ivoa.net/xml/StandardsRegExt/v1.0 does not have this problem IVOA.PaulHarrison
   1. Section 2.3: I think there's a typo somewhere in the phrase "...IVOA identifier given by &lt;identifier&gt;ivo://ivoa.net/std/QueryProtocol&lt;identifier&gt;", but perhaps I'm just misunderstanding it
   1. Section 3.1.1: the example at the end of this section has an endorsedVersion element with status="pr".  According to the list of allowed values, it should have the value "prop" instead.  However, it might be better to change the list of allowed values to rec/pr/wd rather than rec/prop/wd, for consistency and to match usual IVOA usage.
   1. The !StandardKey/description element is declared with type xs:token, which as I understand it means that it can't contain line breaks etc.  That's OK, but probably the documentation should point out that it's for a short description so people know that a multi-paragraph entry is not appropriate.  Or, define it as some other data type (xs:string) suitable for longer descriptions.
   1. Miscellaneous typos:
      * "The Virtual Observatory (VO) is general term..."
      * "...standards would represented via..."
      * "...schema call StandardsRegExt which allows..."
      * "complient"
      * "...onto IVOA identifier associated with..."
      * "...VOResource standard the defines extra..."
      * "...a controlled sets of..."
      * "...is that growing list of allowed names..." (-> growing the list?)
      * "...it is the practice VOResource..."
      * "...as a resource available via an IVOA-compliant registry..." (-> a resource is available?)
      * "... if there is only one standard ce, role..."
      * "An applications can..."
      * "...dereferencing in not necessary..."
         * corrected in latest draft IVOA.PaulHarrison
   2. Document processing: the section numbers appear twice in section headings (e.g. "3.1.2. 3.1.2. !ServiceStandard")
      * there was some javascript that was auto-numbering as well - this has been removed in latest draft IVOA.PaulHarrison
