@@ -5,7 +5,7 @@ The `infoblox_txt_record` resource associates a text value with a domain name.
 The following list describes the parameters you can define in the resource block of the record:
 
 * `fqdn`: required, specifies the fully qualified domain name which you want to assign the text value for. Example: `host43.zone12.org`
-* `text`: required, specifies the text value for the TXT-record. An empty value is not allowed.
+* `text`: required, specifies the text value for the TXT-record. It can contain substrings of up to 255 bytes and a total of up to 512 bytes. If you enter leading, trailing, or embedded spaces in the text string, enclose the entire string within `\"` characters to preserve the spaces.
 * `dns_view`: optional, specifies the DNS view which the zone exists in. If a value is not specified, the name `default` is used for DNS view. Example: `dns_view_1`
 * `ttl`: optional, specifies the "time to live" value for the record. There is no default value for this parameter. If a value is not specified, then in NIOS, the value is inherited from the parent zone of the DNS record for this resource. A TTL value of 0 (zero) means caching should be disabled for this record. Example: `600`
 * `comment`: optional, describes the record. Example: `auto-created test record #1`
