      Write an annotated string, using an indexed attribute, into the encoding. Multiple attributes with a shared name can be written to the same element by calling this method multiple times with a different index value. The encoding will use attribute ids up to the base id plus the maximum index passed in. Implementors must be careful to not use other attributes with ids bigger than the base id within the element taking the indexed attribute.

      writeStringIndexed in interface Encoder
      Parameters:
      attribId - is the shared AttributeId
      index - is the unique index to associated with the string
      val - is the string to encode
      Throws:
      IOException - for errors in the underlying stream

      Specified by:
      writeSpace in interface Encoder
      Parameters:
      attribId - is the given AttributeId annotation
      spc - is the address space to encode
