mixed

Description

The mixed pattern is a shortcut for interleave with an embedded text pattern. It describes unordered content models in which a text node may be included before and after each element. Note that RELAX NG doesn’t allow adding constraints to these text nodes.

Restrictions

The limitations of interleave apply here:

• The mixed pattern can’t be used within a list.

• Elements within a mixed pattern can’t have overlapping name classes.

• There must no other text pattern in each set of patterns combined by mixed.

Example

element title {
 mixed {
  attribute xml:lang {text}&
  element a {attribute href {text}, text} *
 }
}
is equivalent to:
element title {
 ( text & (
  attribute xml:lang {text}&
  element a {attribute href {text}, text} *
 )
}
which itself is equivalent to:
element title {
  text & 
  attribute xml:lang {text}&
  element a {attribute href {text}, text} *
}
