<classSpec>

<classSpec> (class specification) contains reference information for a TEI element class; that is a group of elements which appear together in content models, or which share some common attribute, or both.
Module tagdocs — 22 Documentation Elements
In addition to global attributes att.identified (@ident, @predeclare, @module, @mode)
type indicates whether this is a model class or an attribute class
Status Required
Legal values are:
model
(content model) members of this class appear in the same content models
atts
(attributes) members of this class share common attributes
generate indicates which alternation and sequence instantiations of a model class may be referenced. By default, all variations are permitted.
Status Optional
Datatype 1–5 occurrences of  

<rng:ref name="data.enumerated"/>
data.enumerated
separated by whitespace
Legal values are:
alternation
members of the class are alternatives
sequence
members of the class are to be provided in sequence
sequenceOptional
members of the class may be provided, in sequence, but are optional
sequenceOptionalRepeatable
members of the class may be provided one or more times, in sequence, but are optional.
sequenceRepeatable
members of the class may be provided one or more times, in sequence

Example
<classSpec module="tei" type="model" ident="model.segLike">
 <desc>groups elements used for arbitrary segmentation. </desc>
 <classes>
  <memberOf key="model.phrase"/>
 </classes>
 <remarks>
  <p>The principles on which segmentation is carried out, and
     any special codes or attribute values used, should be defined explicitly
     in the <gi>segmentation</gi> element of the <gi>encodingDesc</gi> within
     the associated TEI header.</p>
