 *
 A transaction body for an `appendContent` transaction.<br/>
 This transaction body provides a mechanism to append content to a "file" in
 network state. Hedera transactions are limited in size, but there are many
 uses for in-state byte arrays (e.g. smart contract bytecode) which require
 more than may fit within a single transaction. The `appendFile` transaction
 exists to support these requirements. The typical pattern is to create a
 file, append more data until the full content is stored, verify the file is
 correct, then update the file entry with any final metadata changes (e.g.
 adding threshold keys and removing the initial upload key).

 Each append transaction MUST remain within the total transaction size limit
 for the network (typically 6144 bytes).<br/>
 The total size of a file MUST remain within the maximum file size limit for
 the network (typically 1048576 bytes).

 #### Signature Requirements
 Append transactions MUST have signatures from _all_ keys in the `KeyList`
 assigned to the `keys` field of the file.<br/>
 See the [File Service](#FileService) specification for a detailed
 explanation of the signature requirements for all file transactions.
