// Node's attributes are mostly used during Storage Policy evaluation to
// calculate object's placement and find a set of nodes satisfying policy
// requirements. There are some "well-known" node attributes common to all the
// Storage Nodes in the network and used implicitly with default values if not

//
// * Capacity \
// Total available disk space in Gigabytes.
// * Price \
// Price in GAS tokens for storing one GB of data during one Epoch. In node
// attributes it's a string presenting floating point number with comma or
// point delimiter for decimal part. In the Network Map it will be saved as
// 64-bit unsigned integer representing number of minimal token fractions.
// * Subnet \
// String ID of Node's storage subnet. There can be only one subnet served
// by the Storage Node.
// * Locode \
// Node's geographic location in
// [UN/LOCODE](https://www.unece.org/cefact/codesfortrade/codes_index.html)
// format approximated to the nearest point defined in standard.
// * Country \
// Country code in

// * City \
// City, town, village or rural area name where node is located written
// without diacritics . Calculated automatically from `Locode` attribute.
//
// For detailed description of each well-known attribute please see the
