Overview

Priority 0: Inherit parent’s default namespace

When parent uses default format (xmlns=“uri”), children in same namespace should inherit by having NO prefix (not parent’s prefix!)

This handles two cases:

  1. Parent has explicit namespace_class in same namespace

  2. Parent has default namespace declared (child’s namespace matches parent’s default)

Instance Method Details

#applies?(context) ⇒ Boolean

Applies when:

  • Parent uses default format

  • Element is in same namespace as parent (explicit OR via default)

  • Child does NOT have its own prefix from deserialization (if child has its own prefix, FormatPreservationRule should handle it)

Returns:

  • (Boolean)
