- Improved implementation of operations in the file system:
    - Redirects from http -> https are now followed.
    - Added support for http(s) methods "put", "delete", "head", "patch", "trace" and "options". Many thanks to LambdaWerk GmbH for sponsoring this improvement.

————————————————————————
Changes in MorganaXProc 1.0.11 (2017-12-30)
Highlight of this release is a new mechanism implemented to support the use of different XSL-FO-processor in p:xsl-formatter:
- The hard coded connection from MorganaXProc to Apache™ FOP is removed in favour of a new FOConnector interface. This interface can be used for XSL-FO processing with any conformant FO-processor.
- Two new implementations of FOConnectors for Apache™ FOP version 1.1 and version 2.2 are supplied with MorganaXProc's standard distribution.
- Parameters can now be passed to both FOConnectors using p:xsl-formatter's parameter port.
Additional changes:
- Changed algorithm for resolving relative URIs in options against the base-uri: If option is an empty string, the base-uri is returned, no longer the parent of the base-uri.
- Checked with SaxonHE 9.7.0.21
- Checked with SaxonHE 9.8.0.7: Due to changes in Saxon 9.8.0.7 ISO schematron implementation works with p:validate-with-schematron again when this Saxon version is used.

————————————————————————
Changes in MorganaXProc 1.0.10 (2017-12-05)
This service update improves the usability of p:xslt and p:validate-with-schematron:

- Improved error message in p:xslt when a text node appears in the result tree before an element node.
- Fixed a bug in p:validate-with-schematron preventing the use of different parameter sets without restart.
- New feature: Parameters on p:validate-with-schematron are now also submitted to the validation itself (phase 4 of the skeleton implementation). 

————————————————————————
Changes in MorganaXProc 1.0.9 (2017-11-05)
It is a service release fixing some bugs:

- Fixed a bug where a single variable reference with a prefixed option- or variable name is not correctly resolved in p:with-param.
- Minor changes in MorganaXPath's ModelNode interface on the way to XProc 3.0.
- Changed XQueryConfiguration for VariableResolvers: You can now set a resolver providing declarations (for static analysis) and another providing the actual values (during dynamic analysis).

- Checked with SaxonHE 9.8.0.6.

————————————————————————
Changes in MorganaXProc 1.0.8 (2017-10-08)
It is a service release fixing some bugs, improving error messages and adding some new features in the XPath implementation on the way to XProc 3.0:

- Fixed a bug leading to an error message when constructing an empty document node in XQuery.
- Fixed a bug leading to NullPointerException when a http-request does not return an entity body (http response 204)
- On the way to XProc 3.0 class "XQueryDocument" was renamed to "XdmDocument".
- Added security checks for HTTP method "patch", "option" and "trace".
- Fixed misleading error code: Double binding of one input port now results in XS0011.
- XPath/XQuery: Added new diagnostic method discovering variables used in the expression and deciding whether the expression relies on the context item.
- XPath/XQuery: Updated interface "XPathFunction" so a function can declare dependence on the context item.
- Changed a misleading error message "Missing scheme in absolute URI reference" that appear with p:document, but actually is not related to @href but says, that in the document to load there is a namespace binding with an URI not conforming to RFC 3986 because  URI has no scheme (which required). Thanks to Felix for pointing this out to me.
- Clarified error message when p:import is used in the wrong place.
- Just changed generic Exception thrown in XQueryNodeModel to "XQueryAddingException" to better reflect cause of exception.
- On the way to XProc 3.0: Added static method "compileSequenceType" in SequenceTypeCompiler.

- Checked with Saxon 9.8.0.4 and 9.8.0.5.

————————————————————————

- Improved attribute creation with names in namespaces: Using existing prefixes if possible.
