Note

Although the msDesc has primarily been designed with a view to encoding manuscript descriptions, it may also be used for other objects such as early printed books, fascicles, epigraphs, or any text-bearing objects that require substantial description. If an object is not text-bearing or the reasons for describing the object is not primarily the textual content, the more general object may be more suitable.
Example

 </msContents>
 <physDesc>
  <objectDesc>
   <p>A parchment codex of 136 folios, measuring approx
       28 by 19 inches, and containing 24 quires.</p>
   <p>The pages are margined and ruled throughout.</p>
   <p>Four hands have been identified in the manuscript: the first 44
       folios being written in two cursive anglicana scripts, while the
       remainder is for the most part in a mixed secretary hand.</p>

Schematron

<sch:rule context="tei:msContents|tei:physDesc|tei:history|tei:additional">

<!-- Note: This rule applies to <msContents>, <physDesc>, <history>, and <additional> wherever they occur. Luckily they are only allowed in places where they are constrained to 0 or 1 occurence. If that changes someday, this constraint may will likely need to be updated, too. -->

<!-- Also worth noting that a) if &amp; when we can use abstract patterns, this would be better handled as a single abstract rule somewhere, and concrete rules in the individual <elementSpec>s; and b) I did not test for the existence of "../*[name(.) eq $gi][2]" because then an error would be generated for each of the multiple occurences of $gi. -->
<sch:let name="gi" value="name(.)"/>
<sch:report test="preceding-sibling::*[ name(.) eq $gi ] and not( following-sibling::*[ name(.) eq $gi ] )"> Only one <sch:name/> is allowed as a child of <sch:value-of select="name(..)"/>.
