Declared in <balxml_namespaceregistry.h>

Return the integer ID for the specified namespaceUri or ‐1 if the namespace has not been registered. Note that not all negative return values correspond to unregistered namespaces. Preregistered namespaces always have negative IDs. (See "Preregistered Namespaces" in the balxml_namespaceregistry component‐level documentation.) Note that a return value of ‐1 can mean either an unregistered namespace or an empty URI string. This dual‐use of ‐1 is deliberate and simplifies error handling in most clients.
