| Attributes |
| Name |
Value |
Description |
| src |
URI |
The URI specifying the location of the grammar, if it is external. |
| scope |
"document" or "dialog" |
Either "document", which makes the grammar active in all dialogs of the current document (and relevant application leaf documents), or "dialog", to make the grammar active throughout the current form. If omitted, the grammar scoping is resolved by looking at the parent element. |
| type |
mime-type |
The MIME type of the grammar. If this is omitted, the interpreter context will attempt to determine the type dynamically. |
| caching |
'safe' or 'fast' |
Eithere safe to force a query to fetch the most recent copy of the content, or fast to use the cached copy of the content if it has not expired. If not specified, a value derived from the innermost caching property is used. |
| fetchint |
"prefetch", "safe", "stream" |
Defines when the interpreter context should retreive content from the server. prefetch indicates a file may be downloaded when the page is loaded, whereas safe indicates a file that should only be downloaded when actually needed. In the case of a very large file (implying long download times) or a streaming audio source, stream indicates to the interpreter context to begin processing the content as it arrives and should not wait for full retrieval of the content. If not specified, a value derived from the innermost relevant *fetchint property is used. |
| fetchtimeout |
integer |
The interval to wait for the content to be returned before throwing an error.badfetch event. If not specified, a value derived from the innermost fetchtimeout is used. |
