	return metadata.orElse(null);

[nitpick] Consider initializing the ConcurrentHashMap.newKeySet() with an expected size to avoid unnecessary resizing operations during bulk indexing operations.

Suggested change

	Set<IndexMetadataTask> batchIndex = ConcurrentHashMap.newKeySet();
	Set<IndexMetadataTask> batchIndex = ConcurrentHashMap.newKeySet(32);

[nitpick] The magic number 0 for the 'from' parameter should be extracted as a named constant for better readability.

[nitpick] The comment 'Attribute is created and set after.' could be more descriptive about when and where the attribute creation happens.

Suggested change

	existingElement = false; // Attribute is created and set after.
	// Attribute will be created and set in a subsequent step after the element traversal is complete,
	// typically handled after the XPath navigation loop when the attribute name and value are available.
	existingElement = false;

	// Attribute will be created and set in a subsequent step after the element node is processed,
	// specifically when the code handling attribute creation is executed after this block.
