XPath 2.0 Specification

Loads a document identified by its URI

The way the URI is handled depends on the `URIResolver` in use. The standard URI resolver has an option (set using -p on the command line, or via options on the `Configuration` or `TransformerFactory` classes) to recognize query parameters in the URI. These are keyword=value pairs, separated by semicolons or ampersand characters, giving options for parsing the file located via the URI. The options that are recognized are:

- `validation=strict|lax|preserve|strip`: determines how the input document will be validated. The options "strict" and "lax" require Saxon-SA.

- `strip-space=yes|no|ignorable`: determines whether whitespace-only text nodes will be stripped from the source document. (Such nodes are stripped if this is requested either using this option, or using xsl:strip-space declarations in the stylesheet.) The value "ignorable" causes whitespace text nodes to be stripped if they belong to an element defined in a DTD or schema as having element-only content.

- `parser=full.class.name`: determines the name of the parser (XMLReader) to be used to parse this input file. For example, `parser=org.ccil.cowan.tagsoup.Parser` causes John Cowan's TagSoup parser for HTML to be used.
